Usage

The Knowledge MCP Server provides the following tools:

Managing Project Instructions

Get project instructions: Retrieve the main project instructions (replaces CLAUDE.md)
Update project instructions: Create or update main project instructions

Knowledge Documents

Create knowledge file: Create structured documents with metadata and chapters
Search knowledge: Full-text search across all project documents
Update chapter: Modify specific chapters within documents
Delete knowledge file: Remove knowledge documents

Resources (Read-only)

knowledge://projects/{project_id}/main - Read main project instructions
knowledge://projects/{project_id}/files - List all knowledge files
knowledge://projects/{project_id}/chapters/{filename} - List chapters in a document

Storage Location

Knowledge is stored in your home directory:

~/.knowledge-mcp/
└── projects/
    └── {git-remote-url}/      # Project identified by git remote
        ├── main.md            # Main project instructions
        └── knowledge/         # Knowledge documents
            └── *.md           # Individual knowledge files

Document Format

Knowledge documents use YAML frontmatter with markdown content:

---
title: API Documentation
keywords: [api, rest, endpoints]
---

# Introduction
Overview of the API...

## Chapter: Authentication
How to authenticate with the API...

## Chapter: Endpoints
Available API endpoints...
