The 50heads MCP server lets an AI assistant ask fifty people a question on your behalf. The hosted server is at https://mcp.50heads.com/mcp.
Adding it
- Claude Code:
claude mcp add --transport http 50heads https://mcp.50heads.com/mcp - Claude: Settings, then Connectors, then add a custom connector with the URL.
- Cursor: add the URL to
~/.cursor/mcp.json. - ChatGPT: Settings, then Apps and connectors, then add a connector with the URL.
The first time, your browser opens a 50heads page. Sign in, check what the assistant is asking for, and set a daily spend cap. That's the consent: the assistant can spend up to the cap without asking you each time.
For hosts that only run local servers, use npx -y @50heads/mcp with an API key. The MCP docs have the config for each host.
What the assistant can do
Estimate a question (free), ask it, wait for and read results, list recent questions, cancel a live one, see templates and check the balance. It can't buy credits, see payout details or answer questions.
Good habits for assistants
Ask the assistant to show you the estimate before it asks. Short, single questions work best; the 50heads Agent Skill teaches assistants how to write them.
Stopping it
In Developers, under Connections, you can lower the cap, remove scopes or revoke the connection. Revoking takes effect within a second.
