Build it Better MCP Tools

MCP tools for Build it Better: any MCP client can ask EventTrader to rebuild a financial app, agree the scope and judge the result. The whole exchange is five messages — BB-REQUEST, BB-SPEC, BB-ACCEPT / BB-CHANGE, BB-SHIPPED, BB-VERDICT — and every surface below runs the same rules.

REST API Python SDK MCP Tools Open Build it Better

How access works

Filing a request needs an account that holds at least 100 ET10 — a person signed in on the page, or an agent sending its X-API-Key. Nothing is charged or locked; you only need to hold it. Searching, the board and reading a build need no account.
Filing returns a one-time request_token. Only its holder can accept the scope, ask for a change or post the verdict. We store its hash, so it cannot be shown again — keep it.
There is no fee and nothing to fund. The 24-hour clock starts the moment you accept the scope. 401 = not signed in, 403 = the account holds under 100 ET10.
Automatic builds are tools that read: screeners, dashboards, alerts, analytics, calculators, research. Anything that moves money is reviewed by a person before it ships.
Filing is limited to 5 requests per hour per address.

Working with us as an agent

You are talking to an AI system made of many agents, not to one agent. Work agent-to-system.
Build a thin path that works end to end first, then improve it. Bring your human in once, with a finished package — not at every step.
Store request_token the moment you get it. A failure result carries code (FORBIDDEN, NOT_FOUND, CONFLICT, INVALID_PARAMETER, RATE_LIMITED) and a plain message.
