A refused API key is the 401. The caller''s own answer: Cache-Control private, no-store.'

description: 'JSON-RPC 2.0 over POST: initialize, tools/list, tools/call. Each request stands alone (no session id); answers are JSON (Accept must list application/json and text/event-stream). The tools are read-only, one per JSON route, answering that route as structuredContent (sponsor_templates answers the house scoring templates themselves, at the dataset scale GET /api/sponsor/terms names), except set_contact, set_username and set_bio, which write only the caller''s own data (its email and phone, POST /api/me/contact, and its username and its bio, PATCH /api/me/profile), step_up_challenge, which asks for the message a wallet on the caller''s account signs to confirm a contact or username change (POST /api/me/step-up: a challenge good for one call), post_comment, which posts a comment in the caller''s name (POST /api/competitions/:slug/comments, through the site''s comment pipeline: published, held for a moderator or refused; list_comments only reads), the claim tools claim_prize, claim_clearance and claim_submit, which claim the caller''s own prizes through the site''s claim routes (the claim form a prize paid by transfer takes, POST /api/submissions/:id/claim, and an on-chain prize''s screen and its signed claim transaction, POST /api/claims/:id/clearance and /submit; list_prizes and get_claim only read), and the sponsor tools proposal_create, proposal_update, proposal_checks, proposal_request_setup, proposal_deposit and proposal_withdraw, which write only the caller''s own proposals (the /api/sponsor routes).

summary: MCP, read-only (streamable HTTP, stateless, no credentials)
description: 'POST /mcp''s JSON-RPC 2.0 transport listing only each tool that reads and needs no account (readOnlyHint true, not the account''s own), for the directories that list a server without credentials: no tool that writes or reads the caller''s own account is listed, nor any sponsor tool, nor get_result or get_deadline_commitment (their routes answer an error until a competition''s prizes are escrowed on chain or its final is committed: POST /mcp keeps them), and tools/call answers one as a tool this server does not have. It takes no credentials: a cookie or an x-api-key is ignored, and every tool answers as to a signed-out caller. Its initialize instructions are its own, short, and its tools are described for a caller with no account, with no outputSchema: a tool answers its JSON once, as a text block (no structuredContent). The tools that write, and the caller''s own entries, prizes and account, are POST /mcp''s with an API key. GET and DELETE answer 405.'
