*Version: 1.6.4*

## Overview

This project started out as a python wrapper for ServiceNow, but since the dawn of standards like
Model Context Protocol (MCP) and Agent2Agent (A2A) Agent. This Agent has solved the issue with **tons** of MCP tools by distributing those tools to **child agents**.
This allows you to run this entire agent on a small context window and maintain blazing speed! A 10K Context token minimum recommended, although I got away with 4K in some tests using qwen-4b on default settings.

This repository has become a sandbox for some brand new and pretty cool features with respects to each of those.
The original APIs should remain stable,
but please note, the latest features like A2A may still be unstable as it is under active development.

This project now includes an MCP server, which wraps all the original APIs you know and love in the base project. This
allows any MCP capable LLM to leverage these tools and interact with ServiceNow. The MCP Server is enhanced with
various authentication mechanisms, middleware for observability and control,
and optional Eunomia authorization for policy-based access control.

ServiceNow A2A implements a multi-agent system designed to manage and interact with ServiceNow tasks through a delegated,
specialist-based architecture. Built using Python, it leverages libraries like `pydantic-ai` for agent creation,
`FastMCPToolset` for integrating Model Context Protocol (MCP) tools, and `Graphiti`
for building a temporal knowledge graph from official ServiceNow documentation.
The system runs as a FastAPI server via Uvicorn, exposing an Agent-to-Agent (A2A) interface for handling requests.
`pydantic-ai` is able to expose your agent as an A2A agent out of the box with `.to_a2a()`.
This allows this agent to be integrated in
any agentic framework like `Microsoft Agent Framework` (MAF) or `crew.ai`.
The core idea is a **Supervisor Agent** that acts as an intelligent router. It analyzes user queries and assigns tasks to specialized **child agents**,
each focused on a specific domain (e.g., incidents, change management).
Child agents have access to filtered MCP tools and a shared knowledge graph for reasoning over documentation,
ensuring accurate and context-aware executions without direct access to the underlying APIs from the orchestrator.

This architecture is optimized for:
- **Speed**: Parallel execution potential and smaller context windows per agent.
- **Context Usage**: Each agent only loads the tools and skills relevant to its domain, allowing the system to handle hundreds of MCP tools without exceeding token limits or confusing the LLM.
- **Modularity**: New domains can be added as simple child agents without touching the core supervisor logic.

This architecture promotes modularity, scalability, and maintainability, making it suitable for enterprise
integrations with platforms like ServiceNow.

## A2A Agent

### Architecture Summary

The system follows a hierarchical multi-agent design:
- **Orchestrator Agent**: Acts as the entry point, parsing user requests and delegating to child agents based on domain tags.
- **Child Agents**: Domain-specific specialists (one per tag, e.g., "cmdb", "incidents") that execute tasks using filtered MCP tools and query the knowledge graph for guidance from official docs.
- **Knowledge Graph (Graphiti)**: A centralized, temporal graph database ingesting ServiceNow documentation, accessible by child agents for retrieval-augmented reasoning.
- **MCP Tools**: Distributed via tags to ensure each child agent only accesses relevant tools, preventing overload and enhancing security.
- **Server Layer**: Exposes the orchestrator as an A2A API using `pydantic-ai`'s `to_a2a` method and Uvicorn.

Key integrations:
- **Pydantic-AI**: Used for defining agents, models (e.g., OpenAI, Anthropic), and run contexts.
- **A2A (Agent-to-Agent)**: Enables inter-agent communication through delegation tools.
- **Graphiti**: Builds a corpus from URLs of official docs, supporting backends like Kuzu (local), Neo4j, or FalkorDB.
- **FastMCPToolset**: Provides MCP wrappers for ServiceNow APIs, filtered by tags for distribution.

The script initializes the graph on startup (ingesting docs if needed), creates child agents with tag-filtered tools and graph access, builds the supervisor with delegation tools, and launches the server.

This diagram shows the flow from user input to delegation, tool execution, and knowledge retrieval. The orchestrator synthesizes results from children before responding.

### Breakdown

#### 1. Pydantic-AI Integration
Pydantic-AI is the backbone for agent modeling and execution. Agents are created using the `Agent` class, which takes an LLM model (e.g., OpenAIChatModel), system prompt, tools/toolsets, and a name.

- **Model Creation**: The `create_model` function supports multiple providers (OpenAI, Anthropic, Google, HuggingFace) via environment variables or CLI args.
- **RunContext**: Used in tool functions for contextual execution.
- **Agent Hierarchy**: Orchestrator has delegation tools (async functions wrapping child `agent.run()` calls). Children have MCP toolsets and Graphiti tools.

This enables structured, type-safe agent interactions with Pydantic validation.

### 2. A2A (Agent-to-Agent) Framework
A2A facilitates communication between agents:
- The orchestrator is converted to an A2A app via `agent.to_a2a()`, defining skills (high-level capabilities per tag).
- Delegation tools are async callables named `delegate_to_{tag}`, allowing the orchestrator to invoke children dynamically.
- This distributes workload, with the orchestrator synthesizing outputs for a cohesive response.

### 3. Multiple Agents
- **Orchestrator**: Analyzes queries to identify domains (tags), delegates via tools, and combines results. System prompt emphasizes delegation without direct action.
- **Child Agents**: One per tag in `TAGS` list (e.g., "incidents", "cmdb"). Each has a focused system prompt, filtered tools, and Graphiti access.
- **Creation Flow**: In `create_orchestrator`, children are instantiated in a loop, stored in a dict, and wrapped as tools for the parent.

This multi-agent setup scales by adding tags/children without refactoring the core.

### 4. Distribution of MCP Tools via Tags
MCP tools (from `FastMCPToolset`) wrap ServiceNow APIs. Distribution:
- Tools are tagged (e.g., "incidents" for incident-related endpoints).
- In `create_child_agent`, the toolset is filtered: `filtered_toolset = toolset.filtered(lambda ctx, tool_def: tag in (tool_def.tags or []))`.
- This ensures each child only sees relevant tools, reducing complexity and potential misuse.

Example: The "incidents" child gets tools like incident creation/query, while "cmdb" gets CMDB-specific ones.

### 5. Corpus of Knowledge from Official Documentation (Graphiti)
- **Initialization**: `initialize_graphiti_db` creates a Graphiti instance with the chosen backend (Kuzu for local, Neo4j/FalkorDB for servers).
- **Ingestion**: If the graph is empty or `--graphiti-force-reinit` is set, it fetches and adds episodes from `INITIAL_DOC_URLS` (ServiceNow API refs, guides).
- **Temporal Aspect**: Graphiti's episodes preserve dates for version-aware queries.
- **Access by Children**:
    - For Kuzu (embedded): Custom tools `ingest_to_graph` and `query_graph` wrap Graphiti methods.
    - For servers: Uses a separate `FastMCPToolset` for Graphiti MCP, filtered by tag.
- **Usage**: Children query the graph (e.g., "Retrieve details for Table API") to inform tool calls, enabling retrieval-augmented generation (RAG) over docs.

This creates a dynamic corpus, allowing agents to "understand" APIs without hardcoding.

```

This sequence highlights delegation, knowledge retrieval, and tool execution.

### Strengths
- **Modularity & Scalability**: Tags allow easy addition of domains (e.g., new ServiceNow modules) by extending `TAGS` and MCP tools. Graphiti scales with more docs via incremental ingestion.
- **Knowledge-Driven Reasoning**: By ingesting official docs, children can handle evolving APIs (e.g., Zurich bundle updates) without code changes—queries adapt to temporal data.
- **Efficiency**: Tool filtering prevents overload; delegation parallelizes tasks (though sequential in code, extensible to async).
- **Flexibility**: Supports multiple LLMs/backends via args/envs; A2A enables integration with other systems.
- **Minimal Setup**: Graph auto-initializes; defaults make it runnable out-of-box (assuming MCP/Graphiti servers).

#### Features:
- **Authentication**: Supports multiple authentication types including none (disabled), static (internal tokens), JWT, OAuth Proxy, OIDC Proxy, and Remote OAuth for external identity providers.
- **Middleware**: Includes logging, timing, rate limiting, and error handling for robust server operation.
- **Eunomia Authorization**: Optional policy-based authorization with embedded or remote Eunomia server integration.
- **Resources**: Provides `instance_config` and `incident_categories` for ServiceNow configuration and data.
- **Prompts**: Includes `create_incident_prompt` and `query_table_prompt` for AI-driven interactions.
- **OIDC Token Delegation**: Supports token exchange for ServiceNow API calls, enabling user-specific authentication via OIDC.
- **OpenAPI JSON Tool Import**: Import custom ServiceNow API Endpoints through the OpenAPI JSON generated.

#### Using as an MCP Server

The MCP Server can be run in two modes: `stdio` (for local testing) or `http` (for networked access). To start the server, use the following commands:

Run in stdio mode (default):
```bash
servicenow-mcp --transport "stdio"
```

Run in HTTP mode:
```bash
servicenow-mcp --transport "http"  --host "0.0.0.0"  --port "8000"
```

Run in Production:

**Embedded Eunomia:**
