## 📚 Available Tools

### 1. `get_codebase_files`
Lists all files in a directory (respects `.jympignore`)

**Example:**
```
"List all files in /Users/me/my-app"
```

### 2. `create_codebase_prompt`
Combines all files into a single LLM prompt

**Example:**
```
"Create a codebase prompt for /Users/me/my-app with basic compression"
```

**Parameters:**
- `directory`: Path to your project
- `compression`: `none` or `basic` (optional)

### 3. `create_prompt_from_files`
Combines specific files into a prompt

**Example:**
```
"Combine src/index.ts and src/utils.ts from /Users/me/my-app"
```

**Parameters:**
- `directory`: Base directory path
- `files`: Array of file paths
- `compression`: `none` or `basic` (optional)

***

## ⚙️ Configuration

### Exclude Files with .jympignore

Create a `.jympignore` file in your project root:

```
node_modules
.git
dist
build
.env
*.log
.DS_Store
coverage/
```

The server automatically respects these exclusions.

### Compression Modes

- **`none`** (default): Full file contents
- **`basic`**: Removes comments, blank lines, and compresses whitespace

***

## 🔧 Troubleshooting

### "command not found: jymp-mcp-server" after installation

**Problem:** npm global bin directory not in PATH

**Solution:**

```bash
# Add npm global bin to your PATH
echo 'export PATH="$(npm bin -g):$PATH"' >> ~/.zshrc
source ~/.zshrc

# Then reinstall
npm install -g @mahendra189/jymp-mcp-server

# Find the path
which jymp-mcp-server
```

***

### "Server not running" in Perplexity

**Solutions:**

1. Make sure you used the **full path** from `which jymp-mcp-server`
2. Test the command in Terminal first:
```bash
/your/full/path/to/jymp-mcp-server
```
3. Try removing and re-adding the connector
4. Double-check you copied the path correctly (no typos)

***

### "Could not connect" in Claude Desktop

**Solutions:**

1. **Completely quit** Claude Desktop (Cmd+Q, not just close window)
2. Verify you used the correct full path from `which jymp-mcp-server`
3. Test in Terminal first to ensure it works
4. Check for typos in the config file
5. Make sure the JSON syntax is correct (commas, quotes, etc.)

***

### Permission Errors on macOS

Claude may need disk access permissions:

1. Go to **System Settings → Privacy & Security → Files and Folders**
2. Grant Claude access to the directories you want to scan

***

### Still Having Issues?

Run these diagnostic commands:

```bash
# Check Node.js is installed
node --version

# Check npm is working
npm --version

# List global packages
npm list -g --depth=0

# Find jymp-mcp-server path
which jymp-mcp-server

# Test it directly
$(which jymp-mcp-server)
```

If the last command works, then use that exact path in Perplexity/Claude config.
