Knowledge Base MCP Server

A local MCP (Model Context Protocol) server that enables AI systems like Claude Desktop to search and query a knowledge base.

Features

• Text Search: Search the knowledge base using natural language queries
• Chunk Retrieval: Get specific chunks by ID for detailed information
• Category Listing: Browse available topics in the knowledge base

Installation

# Install dependencies
npm install

# Build the TypeScript code
npm run build

Available MCP Tools

Tool	Description
search_knowledge	Search for relevant information using a query string
get_chunk	Retrieve a specific chunk by its ID
list_categories	List all available categories in the knowledge base

Connecting to Claude Desktop

Add this server to your Claude Desktop configuration:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "knowledge-base": {
      "command": "node",
      "args": ["/path/to/local-mcp-simple/dist/index.js"]
    }
  }
}

After updating the config, restart Claude Desktop. You can then ask Claude to search the knowledge base, for example:

"Search the knowledge base for speed limits in school zones"

Development

# Build and run
npm run dev

# Or run separately
npm run build
npm start

Generating Knowledge Base

You can generate a new knowledge.json from any markdown file using the included script:

# Generate from a markdown file
npm run generate-knowledge -- ./path/to/your-document.md

# Specify output location
npm run generate-knowledge -- ./docs/handbook.md ./src/knowledge/knowledge.json

Markdown Format

The script parses markdown headings to create chunks:

• H1 (#) - Sets the category for subsequent chunks
• H2 (##) - Creates a new chunk with this title
• H3 (###) - Also creates a new chunk with this title
• H4 (####) - Included as bold text within the current chunk

Example markdown:

# Licences

## Getting your driver licence

To get a full driver licence, you need to go through three stages...

## Learner licence restrictions

There are licence restrictions that you need to follow...

# Speed Limits

## The rules

On roads where there's a speed limit sign, you must not drive faster...

This would create 3 chunks:

1. "Getting your driver licence" (category: "Licences")
2. "Learner licence restrictions" (category: "Licences")
3. "The rules" (category: "Speed Limits")

Knowledge Base

The server uses src/knowledge/knowledge.json which contains pre-chunked content for search.
