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 | GPG/SSH signing (enabled by default) for commits, merges, rebases, cherry-picks, and tags. Silent fallback to unsigned on failure with signed/signingWarning fields in responses. |
| 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_DIRrestricts 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
RateLimiterservice. - 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. |
