mcp-gateway

An open-source project by Fetch Hive.

OpenAPI to MCP. Connect your API to Cursor, Codex, Claude Code, VS Code, ChatGPT, or any MCP client — in minutes.

That means a live API, and it also means the API on your laptop: a WIP branch, localhost:3000, a Docker compose stack. Point the editor at the gateway and call the same tools you will ship.

Prefer a hosted MCP Gateway with tokens, quotas, and a dashboard? https://fetchhive.com/mcp

Two equally important flows

1. Local / branch API → editor

Your server is already running on this machine. Compile the OpenAPI, proxy loopback, paste a snippet into Cursor / Codex / Claude Code.

mcp-gateway init --allow-private-networks
mcp-gateway add-spec --name demo --file ./openapi.yaml \
  --base-url http://127.0.0.1:3000 --insecure-http
export MCP_GATEWAY_TOKEN=…   # printed once by init
mcp-gateway test demo list_pets --args '{}'
mcp-gateway serve demo
mcp-gateway inspect demo --client cursor      # or: codex | claude-code | vscode | claude

--allow-private-networks is required for loopback and RFC1918. --insecure-http is required when the API speaks HTTP (typical on localhost). --base-url is the origin of this checkout, not production.

2. Live API → editor or agent

Same compiler, public HTTPS OpenAPI, no private-network flag.

mcp-gateway init
mcp-gateway add-spec --name demo --url https://api.example.com/openapi.json
export MCP_GATEWAY_TOKEN=…
mcp-gateway serve demo
mcp-gateway inspect demo --client cursor

Or skip operating a process: hosted MCP Gateway. PaaS / VPS: deploy.

3. Local server, remote client

The process stays on loopback. An outbound tunnel gives you https://<slug>.mcp.fetchhive.com/mcp for OpenAI, Claude, Cursor, and any other client that can send a bearer header. No account. The URL is released 30 minutes after the CLI exits.

export MCP_GATEWAY_TOKEN=…
mcp-gateway serve demo --tunnel

Details: Tunnel.

Deploy

Guides: Render · Heroku · DigitalOcean · Hetzner. Vercel cannot run this server (why).

Set MCP_GATEWAY_TOKEN and MCP_GATEWAY_SPEC_URL (HTTPS OpenAPI). The image reads PORT itself (distroless, no shell). After deploy, paste mcp-gateway inspect demo --client cursor (replace the URL with your https://…/mcp) into the editor.

Install

# Homebrew — use the fully qualified name (Homebrew 6 trusts only this formula).
# `brew tap` then `brew install mcp-gateway` is refused until you `brew trust`.
brew install Fetch-Hive/tap/mcp-gateway

# Docker (linux/amd64 and linux/arm64)
docker run --rm -p 127.0.0.1:8787:8787 ghcr.io/fetch-hive/mcp-gateway:0.7.1 version

# npm — wrapper plus the prebuilt binary for this machine
npx --yes @fetch-hive/mcp-gateway version

# GitHub Release installer

# From a checkout of this repo
cargo install --path crates/mcp-gateway-cli

mcp-gateway compiles OpenAPI 3.0/3.1 to a versioned IR, serves tools over Streamable HTTP or stdio, and injects upstream credentials from env or file references. Outbound HTTP uses an SSRF-hardened dialer.
