About
OpenClaw's TypeScript bridge for MCPs — call any Model Context Protocol server as if it were a plain TypeScript API, or repackage as a CLI.
What it does
MCPorter gives developers one operating layer for finding, authenticating with, and using MCP servers. It reads its own configuration plus definitions from several coding clients. You can inspect tools, invoke them, read resources, preserve long-running connections, or record sessions for later replay.
Why it's ranked here
The appeal is breadth with a coherent workflow. One tool covers discovery, calls, resources, OAuth, configuration imports, typed client generation, focused command-line generation, session replay, and server bridging. The repository also describes end-to-end protocol fixtures and strict checks before publishing. The main reservation is its demanding runtime baseline and substantial operational scope.
What's good
It supports stdio, Streamable HTTP, and legacy SSE servers. Human-readable output suits terminal work, while JSON supports scripts and agents. Configuration accepts JSON with comments, environment substitution, tool filters, OAuth settings, and lifecycle rules. Connection reuse and a keep-alive daemon reduce repeated startup costs for selected servers.
Tradeoffs
Node 24 or newer is required for npm installs. The large feature surface brings configuration precedence, credential storage, daemon behavior, protocol negotiation, and lifecycle policy into one tool. Headless and daemon-managed calls decline interactive requests. Chrome relay integration also depends on OpenClaw's newer relay capability for its authenticated path.
How to use it well
Use it when developers and coding agents need the same MCP servers across terminal exploration, automation, and TypeScript applications. Start by listing tool signatures, switch to JSON for automation, and keep connections alive only where startup cost warrants it. It does not replace the MCP servers or supply their underlying tools.
Technical notes+
package.json defines an ESM package, a public npm release surface, Node >=24, a CLI binary, library exports, TypeScript declarations, pnpm scripts, and prepublish checks. src/index.ts exposes the runtime, one-shot calls, result wrappers, elicitation responders, proxy support, and daemon helpers. src/runtime.ts implements pooled connections, tool filtering, resources, cached authentication controls, timeouts, and record or replay selection. src/config.ts merges imported and local definitions, with local entries winning. src/oauth.ts handles browser-based authorization and loopback callbacks across macOS, Windows, and other desktop environments. src/oauth-vault.ts persists credentials under locking, while src/fs-json.ts provides atomic writes and stale-lock recovery. src/serve.ts republishes keep-alive servers over stdio or HTTP and namespaces bridged tools.
