# @supermemory/tools

Memory tools for AI SDK, OpenAI, and Mastra with supermemory

This package provides supermemory tools for AI SDK, OpenAI, and Mastra through dedicated submodule exports, each with function-based architectures optimized for their respective use cases.

## Installation

```bash
npm install @supermemory/tools
```

## Usage

The package provides three submodule imports:
- `@supermemory/tools/ai-sdk` - For use with the AI SDK framework (includes `withSupermemory` middleware)
- `@supermemory/tools/openai` - For use with OpenAI SDK (includes `withSupermemory` middleware and function calling tools)
- `@supermemory/tools/mastra` - For use with Mastra AI agents (includes `withSupermemory` wrapper and processors)

### AI SDK Usage

```typescript
import { supermemoryTools, searchMemoriesTool, addMemoryTool } from "@supermemory/tools/ai-sdk"
import { createOpenAI } from "@ai-sdk/openai"
import { generateText } from "ai"

const openai = createOpenAI({
  apiKey: process.env.OPENAI_API_KEY!,
})

// Create all tools
const tools = supermemoryTools(process.env.SUPERMEMORY_API_KEY!, {
  containerTags: ["your-user-id"],
})

// Use with AI SDK
const result = await generateText({
  model: openai("gpt-5"),
  messages: [
    {
      role: "user",
      content: "What do you remember about my preferences?",
    },
  ],
  tools,
})

// Or create individual tools
const searchTool = searchMemoriesTool(process.env.SUPERMEMORY_API_KEY!, {
  projectId: "your-project-id",
})

const addTool = addMemoryTool(process.env.SUPERMEMORY_API_KEY!, {
  projectId: "your-project-id",
})
```

#### AI SDK Middleware with Supermemory

- `withSupermemory` will take advantage supermemory profile v4 endpoint personalized based on container tag
- You can provide the Supermemory API key via the `apiKey` option to `withSupermemory` (recommended for browser usage), or fall back to `SUPERMEMORY_API_KEY` in the environment for server usage.
- **Per-turn caching**: Memory injection is cached for tool-call continuations within the same user turn. The middleware detects when the AI SDK is continuing a multi-step flow (e.g., after a tool call) and reuses the cached memories instead of making redundant API calls. A fresh fetch occurs on each new user message turn.

```typescript
import { generateText } from "ai"
import { withSupermemory } from "@supermemory/tools/ai-sdk"
import { openai } from "@ai-sdk/openai"

const modelWithMemory = withSupermemory(openai("gpt-5"), "user_id_life")

const result = await generateText({
	model: modelWithMemory,
	messages: [{ role: "user", content: "where do i live?" }],
})

console.log(result.text)
```

#### Conversation Grouping

Use the `conversationId` option to group messages into a single document for contextual memory generation:

```typescript
import { generateText } from "ai"
import { withSupermemory } from "@supermemory/tools/ai-sdk"
import { openai } from "@ai-sdk/openai"

const modelWithMemory = withSupermemory(openai("gpt-5"), "user_id_life", {
	conversationId: "conversation-456"
})

const result = await generateText({
	model: modelWithMemory,
	messages: [{ role: "user", content: "where do i live?" }],
})

console.log(result.text)
```

#### Verbose Mode

Enable verbose logging to see detailed information about memory search and transformation:

```typescript
import { generateText } from "ai"
import { withSupermemory } from "@supermemory/tools/ai-sdk"
import { openai } from "@ai-sdk/openai"

const modelWithMemory = withSupermemory(openai("gpt-5"), "user_id_life", {
	verbose: true
})

const result = await generateText({
	model: modelWithMemory,
	messages: [{ role: "user", content: "where do i live?" }],
})

console.log(result.text)
```

When verbose mode is enabled, you'll see console output like:
```
[supermemory] Searching memories for container: user_id_life
[supermemory] User message: where do i live?
[supermemory] System prompt exists: false
[supermemory] Found 3 memories
[supermemory] Memory content: You live in San Francisco, California. Your address is 123 Main Street...
[supermemory] Creating new system prompt with memories
```

#### Memory Search Modes

The middleware supports different modes for memory retrieval:

**Profile Mode (Default)** - Retrieves user profile memories without query filtering:
```typescript
import { generateText } from "ai"
import { withSupermemory } from "@supermemory/tools/ai-sdk"
import { openai } from "@ai-sdk/openai"

// Uses profile mode by default - gets all user profile memories
const modelWithMemory = withSupermemory(openai("gpt-4"), "user-123")

// Explicitly specify profile mode
const modelWithProfile = withSupermemory(openai("gpt-4"), "user-123", { 
  mode: "profile" 
})

const result = await generateText({
  model: modelWithMemory,
  messages: [{ role: "user", content: "What do you know about me?" }],
})
```

**Query Mode** - Searches memories based on the user's message:
```typescript
import { generateText } from "ai"
import { withSupermemory } from "@supermemory/tools/ai-sdk"
import { openai } from "@ai-sdk/openai"

const modelWithQuery = withSupermemory(openai("gpt-4"), "user-123", { 
  mode: "query" 
})

const result = await generateText({
  model: modelWithQuery,
  messages: [{ role: "user", content: "What's my favorite programming language?" }],
})
```

**Full Mode** - Combines both profile and query results:
```typescript
import { generateText } from "ai"
import { withSupermemory } from "@supermemory/tools/ai-sdk"
import { openai } from "@ai-sdk/openai"

const modelWithFull = withSupermemory(openai("gpt-4"), "user-123", { 
  mode: "full" 
})

const result = await generateText({
  model: modelWithFull,
  messages: [{ role: "user", content: "Tell me about my preferences" }],
})
```

#### Automatic Memory Capture

The middleware can automatically save user messages as memories:

**Always Save Memories** - Automatically stores every user message as a memory:
```typescript
import { generateText } from "ai"
import { withSupermemory } from "@supermemory/tools/ai-sdk"
import { openai } from "@ai-sdk/openai"

const modelWithAutoSave = withSupermemory(openai("gpt-4"), "user-123", {
  addMemory: "always"
})

const result = await generateText({
  model: modelWithAutoSave,
  messages: [{ role: "user", content: "I prefer React with TypeScript for my projects" }],
})
// This message will be automatically saved as a memory
```

**Never Save Memories (Default)** - Only retrieves memories without storing new ones:
```typescript
const modelWithNoSave = withSupermemory(openai("gpt-4"), "user-123")
```

**Combined Options** - Use verbose logging with specific modes and memory storage:
```typescript
const modelWithOptions = withSupermemory(openai("gpt-4"), "user-123", {
  mode: "profile",
  addMemory: "always",
  verbose: true
})
```

#### Custom Prompt Templates

Customize how memories are formatted and injected into the system prompt using the `promptTemplate` option. This is useful for:
- Using XML-based prompting (e.g., for Claude models)
- Custom branding (removing "supermemories" references)
- Controlling how your agent describes where information comes from

```typescript
import { generateText } from "ai"
import { withSupermemory, type MemoryPromptData } from "@supermemory/tools/ai-sdk"
import { openai } from "@ai-sdk/openai"

const customPrompt = (data: MemoryPromptData) => `
<user_memories>
Here is some information about your past conversations with the user:
${data.userMemories}
${data.generalSearchMemories}
</user_memories>
`.trim()

const modelWithCustomPrompt = withSupermemory(openai("gpt-4"), "user-123", {
  mode: "full",
  promptTemplate: customPrompt,
})

const result = await generateText({
  model: modelWithCustomPrompt,
  messages: [{ role: "user", content: "What do you know about me?" }],
})
```

The `MemoryPromptData` object provides:
- `userMemories`: Pre-formatted markdown combining static profile facts (name, preferences, goals) and dynamic context (current projects, recent interests)
- `generalSearchMemories`: Pre-formatted search results based on semantic similarity to the current query
- `searchResults`: Raw search results array for traversing, filtering, or selectively including results based on metadata

### OpenAI SDK Usage

#### OpenAI Middleware with Supermemory

The `withSupermemory` function creates an OpenAI client with SuperMemory middleware automatically injected:

```typescript
import { withSupermemory } from "@supermemory/tools/openai"

// Create OpenAI client with supermemory middleware
const openaiWithSupermemory = withSupermemory("user-123", {
  conversationId: "conversation-456",
  mode: "full",
  addMemory: "always",
  verbose: true,
})

// Use directly with chat completions - memories are automatically injected
const completion = await openaiWithSupermemory.chat.completions.create({
  model: "gpt-4o-mini",
  messages: [
    { role: "user", content: "What do you remember about my preferences?" }
  ],
})

console.log(completion.choices[0]?.message?.content)
```

#### OpenAI Middleware Options

The middleware supports the same configuration options as the AI SDK version:

```typescript
const openaiWithSupermemory = withSupermemory("user-123", {
  conversationId: "conversation-456", // Group messages for contextual memory
  mode: "full",                       // "profile" | "query" | "full"
  addMemory: "always",                // "always" | "never"
  verbose: true,                      // Enable detailed logging
})
```

#### Advanced Usage with Custom OpenAI Options

You can also pass custom OpenAI client options:

```typescript
import { withSupermemory } from "@supermemory/tools/openai"

const openaiWithSupermemory = withSupermemory(
  "user-123", 
  {
    mode: "profile",
    addMemory: "always",
  },
  {
    baseURL: "https://api.openai.com/v1",
    organization: "org-123",
  },
  "custom-api-key" // Optional: custom API key
)

const completion = await openaiWithSupermemory.chat.completions.create({
  model: "gpt-4o-mini",
  messages: [{ role: "user", content: "Tell me about my preferences" }],
})
```

#### Next.js API Route Example

Here's a complete example for a Next.js API route:

```typescript
// app/api/chat/route.ts
import { withSupermemory } from "@supermemory/tools/openai"
import type { OpenAI as OpenAIType } from "openai"

export async function POST(req: Request) {
  const { messages, conversationId } = (await req.json()) as {
    messages: OpenAIType.Chat.Completions.ChatCompletionMessageParam[]
    conversationId: string
  }

  const openaiWithSupermemory = withSupermemory("user-123", {
    conversationId,
    mode: "full",
    addMemory: "always",
    verbose: true,
  })

  const completion = await openaiWithSupermemory.chat.completions.create({
    model: "gpt-4o-mini",
    messages,
  })

  const message = completion.choices?.[0]?.message
  return Response.json({ message, usage: completion.usage })
}
```

### OpenAI Function Calling Usage

```typescript
import { supermemoryTools, getToolDefinitions, createToolCallExecutor } from "@supermemory/tools/openai"
import OpenAI from "openai"

const client = new OpenAI({
  apiKey: process.env.OPENAI_API_KEY!,
})

// Get tool definitions for OpenAI
const toolDefinitions = getToolDefinitions()

// Create tool executor
const executeToolCall = createToolCallExecutor(process.env.SUPERMEMORY_API_KEY!, {
  projectId: "your-project-id",
})

// Use with OpenAI Chat Completions
const completion = await client.chat.completions.create({
  model: "gpt-5",
  messages: [
    {
      role: "user",
      content: "What do you remember about my preferences?",
    },
  ],
  tools: toolDefinitions,
})

// Execute tool calls if any
if (completion.choices[0]?.message.tool_calls) {
  for (const toolCall of completion.choices[0].message.tool_calls) {
    const result = await executeToolCall(toolCall)
    console.log(result)
  }
}

// Or create individual function-based tools
const tools = supermemoryTools(process.env.SUPERMEMORY_API_KEY!, {
  containerTags: ["your-user-id"],
})

const searchResult = await tools.searchMemories({
  informationToGet: "user preferences",
  limit: 10,
})

const addResult = await tools.addMemory({
  memory: "User prefers dark roast coffee",
})
```

### Mastra Usage

Add persistent memory to [Mastra](https://mastra.ai) AI agents. The integration provides processors that:
- **Input Processor**: Fetches relevant memories and injects them into the system prompt before LLM calls
- **Output Processor**: Optionally saves conversations to Supermemory after responses

#### Quick Start with `withSupermemory` Wrapper

The simplest way to add memory to a Mastra agent - wrap your config before creating the Agent:

```typescript
import { Agent } from "@mastra/core/agent"
import { withSupermemory } from "@supermemory/tools/mastra"
import { openai } from "@ai-sdk/openai"

// Create agent with memory-enhanced config
const agent = new Agent(withSupermemory(
  {
    id: "my-assistant",
    name: "My Assistant",
    model: openai("gpt-4o"),
    instructions: "You are a helpful assistant.",
  },
  "user-123",  // containerTag - scopes memories to this user
  {
    mode: "full",
    addMemory: "always",
    threadId: "conv-456",
  }
))

const response = await agent.generate("What do you know about me?")
console.log(response.text)
```

#### Direct Processor Usage

For fine-grained control, use processors directly:

```typescript
import { Agent } from "@mastra/core/agent"
import { createSupermemoryProcessors } from "@supermemory/tools/mastra"
import { openai } from "@ai-sdk/openai"

const { input, output } = createSupermemoryProcessors("user-123", {
  mode: "full",
  addMemory: "always",
  threadId: "conv-456",
  verbose: true, // Enable logging
})

const agent = new Agent({
  id: "my-assistant",
  name: "My Assistant",
  model: openai("gpt-4o"),
  instructions: "You are a helpful assistant with memory.",
  inputProcessors: [input],
  outputProcessors: [output],
})

const response = await agent.generate("What's my favorite programming language?")
```

#### Complete Example

Here's a full example showing a multi-turn conversation with memory:

```typescript
import { Agent } from "@mastra/core/agent"
import { createSupermemoryProcessors } from "@supermemory/tools/mastra"
import { openai } from "@ai-sdk/openai"

async function main() {
  const userId = "user-alex-123"
  const threadId = `thread-${Date.now()}`

  const { input, output } = createSupermemoryProcessors(userId, {
    mode: "profile",      // Fetch user profile memories
    addMemory: "always",  // Save all conversations
    threadId,
    verbose: true,
  })

  const agent = new Agent({
    id: "memory-assistant",
    name: "Memory Assistant",
    instructions: `You are a helpful assistant with memory.
Use the memories provided to personalize your responses.`,
    model: openai("gpt-4o-mini"),
    inputProcessors: [input],
    outputProcessors: [output],
  })

  // First conversation - introduce yourself
  console.log("User: Hi! I'm Alex, a TypeScript developer.")
  const r1 = await agent.generate("Hi! I'm Alex, a TypeScript developer.")
  console.log("Assistant:", r1.text)

  // Second conversation - the agent should remember
  console.log("\nUser: What do you know about me?")
  const r2 = await agent.generate("What do you know about me?")
  console.log("Assistant:", r2.text)
}

main()
```

#### Memory Search Modes

- **`profile`** (default): Fetches user profile memories (static facts + dynamic context)
- **`query`**: Searches memories based on the user's message
- **`full`**: Combines both profile and query results

```typescript
// Profile mode - good for general personalization
const { input } = createSupermemoryProcessors("user-123", { mode: "profile" })

// Query mode - good for specific lookups
const { input } = createSupermemoryProcessors("user-123", { mode: "query" })

// Full mode - comprehensive context
const { input } = createSupermemoryProcessors("user-123", { mode: "full" })
```

#### Custom Prompt Templates

Customize how memories are formatted in the system prompt:

```typescript
import { createSupermemoryProcessors, type MemoryPromptData } from "@supermemory/tools/mastra"

const customTemplate = (data: MemoryPromptData) => `
<user_context>
${data.userMemories}
${data.generalSearchMemories}
</user_context>
`.trim()

const { input, output } = createSupermemoryProcessors("user-123", {
  mode: "full",
  promptTemplate: customTemplate,
})
```

#### Using RequestContext for Dynamic Thread IDs

Instead of hardcoding `threadId`, use Mastra's RequestContext for dynamic values:

```typescript
import { Agent } from "@mastra/core/agent"
import { RequestContext, MASTRA_THREAD_ID_KEY } from "@mastra/core/request-context"
import { createSupermemoryProcessors } from "@supermemory/tools/mastra"

const { input, output } = createSupermemoryProcessors("user-123", {
  mode: "profile",
  addMemory: "always",
  // threadId not set here - will be read from RequestContext
})

const agent = new Agent({
  id: "my-assistant",
  name: "My Assistant",
  model: openai("gpt-4o"),
  inputProcessors: [input],
  outputProcessors: [output],
})

// Set threadId dynamically per request
const ctx = new RequestContext()
ctx.set(MASTRA_THREAD_ID_KEY, "dynamic-thread-123")

const response = await agent.generate("Hello!", { requestContext: ctx })
```

#### Mastra Configuration Options

```typescript
interface SupermemoryMastraOptions {
  apiKey?: string              // Supermemory API key (or use SUPERMEMORY_API_KEY env var)
  baseUrl?: string             // Custom API endpoint
  mode?: "profile" | "query" | "full"  // Memory search mode (default: "profile")
  addMemory?: "always" | "never"       // Auto-save conversations (default: "never")
  threadId?: string            // Conversation ID for grouping messages
  verbose?: boolean            // Enable debug logging (default: false)
  promptTemplate?: (data: MemoryPromptData) => string  // Custom memory formatting
}
```

## Configuration

Both modules accept the same configuration interface:

```typescript
interface SupermemoryToolsConfig {
  baseUrl?: string
  containerTags?: string[]
  projectId?: string
  strict?: boolean
}
```

- **baseUrl**: Custom base URL for the supermemory API
- **containerTags**: Array of custom container tags (mutually exclusive with projectId)
- **projectId**: Project ID which gets converted to container tag format (mutually exclusive with containerTags)
- **strict**: Enable strict schema mode for OpenAI strict validation. When `true`, all schema properties are required (satisfies OpenAI strict mode). When `false` (default), optional fields remain optional for maximum compatibility with all models.

### OpenAI Strict Mode Compatibility

When using OpenAI-compatible providers with strict schema validation (e.g., OpenRouter with Azure OpenAI backend), enable strict mode to ensure all schema properties are included in the `required` array:

```typescript
import { searchMemoriesTool, addMemoryTool } from "@supermemory/tools/ai-sdk"
import { createOpenRouter } from "@openrouter/ai-sdk-provider"
import { streamText } from "ai"

const openrouter = createOpenRouter({ apiKey: process.env.OPENROUTER_API_KEY })

const tools = {
  searchMemories: searchMemoriesTool(apiKey, { 
    containerTags: [userId],
    strict: true  // ✅ Required for OpenAI strict mode
  }),
  addMemory: addMemoryTool(apiKey, { 
    containerTags: [userId],
    strict: true
  }),
}

const result = streamText({
  model: openrouter.chat("openai/gpt-5-nano"),
  messages: [...],
  tools,
})
```

Without `strict: true`, optional fields like `includeFullDocs` and `limit` won't be in the `required` array, which will cause validation errors with OpenAI strict mode.

### withSupermemory Middleware Options

The `withSupermemory` middleware accepts additional configuration options:

```typescript
interface WithSupermemoryOptions {
  conversationId?: string
  verbose?: boolean
  mode?: "profile" | "query" | "full"
  addMemory?: "always" | "never"
  /** Optional Supermemory API key. Use this in browser environments. */
  apiKey?: string
}
```

- **conversationId**: Optional conversation ID to group messages into a single document for contextual memory generation
- **verbose**: Enable detailed logging of memory search and injection process (default: false)
- **mode**: Memory search mode - "profile" (default), "query", or "full"
- **addMemory**: Automatic memory storage mode - "always" or "never" (default: "never")

## Available Tools

### Search Memories
Searches through stored memories based on a query string.

**Parameters:**
- `informationToGet` (string): Terms to search for
- `includeFullDocs` (boolean, optional): Whether to include full document content (default: true)
- `limit` (number, optional): Maximum number of results (default: 10)

### Add Memory
Adds a new memory to the system.

**Parameters:**
- `memory` (string): The content to remember



## Claude Memory Tool

Enable Claude to store and retrieve persistent memory across conversations using supermemory as the backend.

### Installation

```bash
npm install @supermemory/tools @anthropic-ai/sdk
```

### Basic Usage

```typescript
import Anthropic from '@anthropic-ai/sdk'
import { createClaudeMemoryTool } from '@supermemory/tools/claude-memory'

const anthropic = new Anthropic({
  apiKey: process.env.ANTHROPIC_API_KEY!,
})

const memoryTool = createClaudeMemoryTool(process.env.SUPERMEMORY_API_KEY!, {
  projectId: 'my-app',
})

async function chatWithMemory(userMessage: string) {
  // Send message to Claude with memory tool
  const response = await anthropic.beta.messages.create({
    model: 'claude-sonnet-4-5',
    max_tokens: 2048,
    messages: [{ role: 'user', content: userMessage }],
    tools: [{ type: 'memory_20250818', name: 'memory' }],
    betas: ['context-management-2025-06-27'],
  })

  // Handle any memory tool calls
  const toolResults = []
  for (const block of response.content) {
    if (block.type === 'tool_use' && block.name === 'memory') {
      const toolResult = await memoryTool.handleCommandForToolResult(
        block.input,
        block.id
      )
      toolResults.push(toolResult)
    }
  }

  return response
}

// Example usage
const response = await chatWithMemory(
  "Remember that I prefer React with TypeScript for my projects"
)
```

### Memory Operations

Claude can perform these memory operations automatically:

- **`view`** - List memory directory contents or read specific files
- **`create`** - Create new memory files with content
- **`str_replace`** - Find and replace text within memory files
- **`insert`** - Insert text at specific line numbers
- **`delete`** - Delete memory files
- **`rename`** - Rename or move memory files

All memory files are stored in supermemory with normalized paths and can be searched and retrieved across conversations.
