MCP Warp

Give your local MCP servers a public, OAuth-protected URL

Like ngrok, but built for MCP. A short setup, then one command, and Claude, ChatGPT and any Streamable HTTP MCP client can securely reach the MCP servers on your machine.

Everything you need to expose an MCP server

OAuth built in

Every public URL is protected by OAuth. No anonymous access, no shared secrets to leak.

stdio and HTTP servers

Expose a spawned stdio process or an already-running Streamable HTTP MCP server, same command.

One URL per server

Each server gets its own subdomain, so OAuth credential caches in your clients never collide.

Built for standard MCP clients

Built for Claude, ChatGPT, VS Code and any Streamable HTTP MCP client.

Streaming end-to-end

Requests flow through with backpressure, from your LLM client to your local server and back.

Dashboard

See every server, its usage, and your plan at web.mcpwarp.io. Enable or disable at will.

How it works

1. Your MCP client sends a request to your server's public URL.
2. The tunnel edge verifies the OAuth token and checks that you own the server.
3. The request is forwarded over a persistent connection to mcpwarp up on your machine.
4. mcpwarp forwards it to your local MCP server, stdio or HTTP, and streams the response back.
