### Description (declared)

# frontmatter-mcp

An MCP server for querying Markdown frontmatter with DuckDB SQL.

## Configuration

### Basic Usage

```json
{
  "mcpServers": {
    "frontmatter": {
      "command": "uvx",
      "args": ["frontmatter-mcp"],
      "env": {
        "FRONTMATTER_BASE_DIR": "/path/to/markdown/directory"
      }
    }
  }
}
```

### With Semantic Search

Semantic search requires large dependencies (~1GB). Set `MCP_TIMEOUT` to extend installation timeout:

```json
{
  "mcpServers": {
    "frontmatter": {
      "command": "uvx",
      "args": ["--from", "frontmatter-mcp[semantic]", "frontmatter-mcp"],
      "env": {
        "FRONTMATTER_BASE_DIR": "/path/to/markdown/directory",
        "FRONTMATTER_ENABLE_SEMANTIC": "true",
        "MCP_TIMEOUT": "300000"
      }
    }
  }
}
```

Note: `MCP_TIMEOUT` is in milliseconds (300000 = 5 minutes).

## Installation (Optional)

If you prefer to install globally:

```bash
pip install frontmatter-mcp
# or
uv tool install frontmatter-mcp
```

## Tools

### query_inspect

    "tags": { "type": "array", "count": 150, "nullable": true }
  }
}

// Output (with semantic search ready)
{
  "file_count": 186,
