Resources

| Resource | URI | Description | | :------------------------ | :------------------------ | :-------------------------------------------------------------------- | | Git Working Directory | git://working-directory | The current session working directory, set via git_set_working_dir. |

| Prompt | Description | Parameters | | :-------------- | :---------------------------------------------------------------------------------------- | :--------------------------------------------------------------------- | | Git Wrap-up | Workflow protocol for completing git sessions: review, document, commit, and tag changes. | changelogPath, skipDocumentation, createTag, updateAgentFiles. |

Getting started

Runtime

Works with both Bun and Node.js. Runtime is auto-detected.

| Runtime | Command | Minimum Version | | ----------- | --------------------------------------- | --------------- | | Node.js | npx @cyanheads/git-mcp-server@latest | >= 20.0.0 | | Bun | bunx @cyanheads/git-mcp-server@latest | >= 1.2.0 |

MCP client configuration

Add the following to your MCP client config (e.g., cline_mcp_settings.json). Update the environment variables to match your setup — especially the git identity fields.

{
  "mcpServers": {
    "git-mcp-server": {
      "type": "stdio",
      "command": "npx",
      "args": ["@cyanheads/git-mcp-server@latest"],
      "env": {
        "MCP_TRANSPORT_TYPE": "stdio",
        "MCP_LOG_LEVEL": "info",
        "GIT_BASE_DIR": "~/Developer/",
        "LOGS_DIR": "~/Developer/logs/git-mcp-server/",
        "GIT_USERNAME": "cyanheads",
        "GIT_EMAIL": "casey@caseyjhand.com",
        "GIT_SIGN_COMMITS": "true"
      }
    }
  }
}

Bun users: replace "command": "npx" with "command": "bunx".

For Streamable HTTP, set MCP_TRANSPORT_TYPE=http and MCP_HTTP_PORT=3015.

Features

Built on mcp-ts-template.

| Feature | Details | | :--------------------------- | :------------------------------------------------------------------------------------------------------------------ | | Declarative tools | Define capabilities in single, self-contained files. The framework handles registration, validation, and execution. | | Error handling | Unified McpError system for consistent, structured error responses. | | Authentication | Supports none, jwt, and oauth modes. | | Pluggable storage | Swap backends (in-memory, filesystem, Supabase, Cloudflare KV/R2) without changing business logic. | | Observability | Structured logging (Pino) and optional auto-instrumented OpenTelemetry for traces and metrics. | | Dependency injection | Built with tsyringe for decoupled, testable architecture. | | Cross-runtime | Auto-detects Bun or Node.js and uses the appropriate process spawning method. | | Provider architecture | Pluggable git provider system. Current: CLI. Planned: isomorphic-git for edge deployment. | | Working directory management | Session-specific directory context for multi-repo workflows. | | Configurable git identity | Override author/committer info via environment variables, with fallback to global git config. | | Commit signing | Optional GPG/SSH signing for commits, merges, rebases, cherry-picks, and tags. | | Safety | Destructive operations (git clean, git reset --hard) require explicit confirmation flags. |

Security

• All file paths are validated and sanitized to prevent directory traversal.
• Optional GIT_BASE_DIR restricts operations to a specific directory tree for multi-tenant sandboxing.
• Git commands use validated arguments via process spawning — no shell interpolation.
• JWT and OAuth support for authenticated deployments.
• Optional rate limiting via the DI-managed RateLimiter service.
• All operations are logged with request context for auditing.

Configuration

All configuration is validated at startup in src/config/index.ts. Key environment variables:

| Variable | Description | Default | | :----------------------------- | :----------------------------------------------------------------------------------------- | :---------- | | MCP_TRANSPORT_TYPE | Transport: stdio or http. | stdio | | MCP_SESSION_MODE | HTTP session mode: stateless, stateful, or auto. | auto | | MCP_RESPONSE_FORMAT | Response format: json (LLM-optimized), markdown (human-readable), or auto. | json | | MCP_RESPONSE_VERBOSITY | Detail level: minimal, standard, or full. | standard | | MCP_HTTP_PORT | HTTP server port. | 3015 | | MCP_HTTP_HOST | HTTP server hostname. | 127.0.0.1 | | MCP_HTTP_ENDPOINT_PATH | MCP request endpoint path. | /mcp | | MCP_AUTH_MODE | Authentication mode: none, jwt, or oauth. | none | | STORAGE_PROVIDER_TYPE | Storage backend: in-memory, filesystem, supabase, cloudflare-kv, r2. | in-memory | | OTEL_ENABLED
