Obsidian GitHub MCP

A Model Context Protocol (MCP) server that connects AI assistants to GitHub repositories containing Obsidian vaults. This server enables seamless integration with your knowledge base stored on GitHub, allowing AI assistants to read, search, and analyze your Obsidian notes and documentation.

Why This Tool?

Many Obsidian users store their vaults in GitHub for backup, versioning, and collaboration. This MCP server bridges the gap between your GitHub-hosted Obsidian vault and AI assistants, enabling:

• Knowledge Base Access: Retrieve specific notes and documents from your Obsidian vault
• Intelligent Search: Find relevant content across your entire knowledge base
• Evolution Tracking: See how your ideas and notes have developed over time
• Task Integration: Connect with issues and project management workflows

Features

• GitHub Repository Access: Connect to any GitHub repository containing your Obsidian vault
• Type-Safe Implementation: Written in TypeScript with comprehensive type definitions
• Input Validation: Robust validation for all API inputs using Zod schemas
• Error Handling: Graceful error handling with informative messages
• MCP Integration: Full compatibility with Claude, Cursor, Windsurf, Cline, and other MCP hosts

Available Tools

Knowledge Base Access

• getFileContents: Retrieve the contents of specific notes, documents, or files from your Obsidian vault
• searchFiles: Enhanced search with multiple modes:
  • filename: Find files by exact filename (perfect for "OKR 2025" type searches)
  • path: Search anywhere in file paths
  • content: Search within file contents
  • all: Comprehensive search across filenames, paths, and content

Project Management Integration

• searchIssues: Search for issues and discussions related to your knowledge base projects
• getCommitHistory: Track how your knowledge base has evolved over time with detailed commit history and diffs

Use Cases

Example Workflows

Accessing Your Daily Notes

{
  "tool": "getFileContents",
  "arguments": {
    "filePath": "Daily Notes/2024-01-15.md"
  }
}

Finding Files by Name (Perfect for "OKR 2025" example!)

{
  "tool": "searchFiles",
  "arguments": {
    "query": "OKR 2025",
    "searchIn": "filename"
  }
}

Finding Files by Path

{
  "tool": "searchFiles",
  "arguments": {
    "query": "Daily Notes",
    "searchIn": "path"
  }
}

Finding Research on a Topic (Content Search)

{
  "tool": "searchFiles",
  "arguments": {
    "query": "machine learning algorithms",
    "searchIn": "content",
    "perPage": 10
  }
}

Comprehensive Search (Filename, Path, and Content)

{
  "tool": "searchFiles",
  "arguments": {
    "query": "project planning",
    "searchIn": "all"
  }
}

Advanced GitHub Search Syntax

{
  "tool": "searchFiles",
  "arguments": {
    "query": "path:*.md extension:md",
    "searchIn": "content"
  }
}

Tracking Knowledge Evolution

{
  "tool": "getCommitHistory",
  "arguments": {
    "days": 30,
    "includeDiffs": true,
    "maxCommits": 10
  }
}

Search Tips & Troubleshooting

Can't Find Your File by Name?

Problem: Searching for "OKR 2025" doesn't find your file named "OKR 2025.md"

Solution: Use the searchIn: "filename" parameter:

{
  "tool": "searchFiles",
  "arguments": {
    "query": "OKR 2025",
    "searchIn": "filename"
  }
}

Advanced Search Techniques

1. Exact Phrases: Use quotes for multi-word searches

   {
     "query": "\"project planning 2025\"",
     "searchIn": "content"
   }
   

2. File Extensions: Find specific file types

   {
     "query": "path:*.md",
     "searchIn": "content"
   }
   

3. Directory Specific: Search within folders

   {
     "query": "path:\"Daily Notes/\"",
     "searchIn": "content"
   }

• pnpm run inspector - Launch MCP inspector for testing

Migration from mcp-private-github-search

If you're migrating from the older mcp-private-github-search package:

1. Update your package name in configuration:

   {
     "mcpServers": {
       "obsidianGithub": {
         "command": "npx",
         "args": ["-y", "obsidian-github-mcp"]
       }
     }
   }
   

2. The functionality remains the same - all existing tools work identically

3. Consider the new Obsidian-focused use cases and workflows
