# Other apps

Connect Windsurf, Zed, Gemini CLI or any MCP client, and bridge apps that only run local servers.

Mr. Market works with any app that supports **remote MCP servers over Streamable HTTP with OAuth sign-in**. The steps
on this site for Claude, Claude Code, ChatGPT, Codex, Cursor and VS Code are the tested ones; the configurations below
follow each app's documented format.

| | |
| --- | --- |
| Server address | `https://mrmarket.fyi/mcp` |
| Transport | Streamable HTTP |
| Auth | OAuth 2.1 with PKCE and dynamic client registration |
| Protected resource metadata | `https://mrmarket.fyi/.well-known/oauth-protected-resource/mcp` |
| Authorization server metadata | `https://mrmarket.fyi/.well-known/oauth-authorization-server` |

There are no API keys for members: every app signs in through the browser.

## Windsurf

In `~/.codeium/windsurf/mcp_config.json`:

```json
{
  "mcpServers": {
    "mr-market": {
      "serverUrl": "https://mrmarket.fyi/mcp"
    }
  }
}
```

## Zed

In Zed's `settings.json` (the root key is `context_servers`):

```json
{
  "context_servers": {
    "mr-market": {
      "url": "https://mrmarket.fyi/mcp"
    }
  }
}
```

## Gemini CLI

```bash
gemini mcp add --transport http mr-market https://mrmarket.fyi/mcp
```

Then run `/mcp auth mr-market` inside Gemini CLI to sign in.

## Apps that only run local servers

Some apps can only start local (stdio) servers. Bridge them with `mcp-remote`, which handles the browser sign-in:

```json
{
  "mcpServers": {
    "mr-market": {
      "command": "npx",
      "args": ["-y", "mcp-remote@latest", "https://mrmarket.fyi/mcp"]
    }
  }
}
```

Use `mcp-remote` 0.1.16 or later; earlier versions had a security flaw (CVE-2025-6514).

## Agent frameworks

Frameworks such as the OpenAI Agents SDK, LangChain or the Vercel AI SDK can connect to `https://mrmarket.fyi/mcp` as a remote
MCP server, but they need an OAuth flow to get a sign-in. Mr. Market doesn't issue API keys to members during the
beta, so these are best driven from an app above.
