upAPI MCP server

upAPI MCP server

Call a catalog of ready-to-use APIs through one upAPI account and key, without signing up for each upstream service.

• Endpoint: https://app.upapi.io/api/mcp (Streamable HTTP, OAuth 2.1)
• Product: https://upapi.io
• Docs: https://upapi.io/docs/mcp

Install

The server is remote, so there is nothing to run locally. It signs you in with OAuth 2.1 (PKCE, dynamic client registration, RFC 9728 metadata): the first time your client calls it, a browser window opens on the upAPI sign-in and consent screen, where you choose what the assistant may do.

Cursor: install the upapi plugin from the Cursor Marketplace, or add the server in one click, or put this in ~/.cursor/mcp.json:

{
  "mcpServers": {
    "upapi": {
      "url": "https://app.upapi.io/api/mcp"
    }
  }
}

Cline: ask Cline to "install the upAPI MCP server from https://github.com/DevinoSolutions/mcp-servers/tree/main/upapi" (it follows llms-install.md), or add this to cline_mcp_settings.json:

{
  "mcpServers": {
    "upapi": {
      "type": "streamableHttp",
      "url": "https://app.upapi.io/api/mcp",
      "disabled": false
    }
  }
}

VS Code (Copilot agent mode): install in one click, or add to .vscode/mcp.json:

{
  "servers": {
    "upapi": {
      "type": "http",
      "url": "https://app.upapi.io/api/mcp"
    }
  }
}

Claude Code: claude mcp add --transport http upapi https://app.upapi.io/api/mcp

Claude and ChatGPT: upAPI is listed in the Claude Connectors Directory and ChatGPT Apps.

Any other MCP client: Streamable HTTP endpoint https://app.upapi.io/api/mcp. It is also published in the official MCP Registry.

How the tools appear

The server runs in Code Mode: tools/list shows search_tools and execute_typescript. The assistant calls search_tools to see the upAPI operations your sign-in reached, then runs them inside execute_typescript as external_<name> functions. Every call keeps the same scopes, confirmations and audit log as a direct call. An operation whose scope you did not grant is never declared.
