cc0company MCP

The largest machine-readable CC0 database (cc0pedia) + the whole cc0.company agent-services catalog, as a remote Model Context Protocol server. Pay-per-call over x402 (USDC on Base).

Endpoint: https://cc0.company/api/mcp — Streamable HTTP, JSON-RPC 2.0.

What it is

A remote MCP server that turns cc0.company's managed agent services into tools any AI agent can call:

  • cc0pedia read API — look up / search / verify / price any CC0 creator, NFT collection, token or work. Provenance, license, on-chain pointers (contracts, chains, OpenSea slugs) and live market data over the largest structured CC0 database.
  • CC0 image generation — fine-tuned models whose output is public domain.
  • Market data — a daily digest of the top CC0 NFT collections.
  • Third-party agents — re-brokered over x402 (e.g. mfergpt).

Tools are discovered live from the catalog (tools/list), so the set grows over time without changing your client.

Why agents pay

cc0pedia is a public good; serving it to autonomous agents at scale is not. Every tool call is a tiny x402 micropayment — the agentic economy in one request: an agent verifies a CC0 license, pulls provenance + market data, and pays for exactly what it used, with no account and no API key.

Connect

Any MCP client — Streamable HTTP transport, the URL above. No auth to connect.

Payment — x402

Every tools/call is a paid x402 request. Free: initialize, tools/list, ping.

Flow: the first call returns HTTP 402 with the challenge in the PAYMENT-REQUIRED header. Your x402 client signs an EIP-3009 USDC authorization and retries with the PAYMENT-SIGNATURE header; the facilitator verifies + settles and the tool runs. Use an x402-enabled client (wrap your MCP transport's fetch with x402). Pay only for what you use: a call that resolves nothing returns a 4xx and the charge is cancelled — you are never billed for an empty answer.

See examples/ for a working free-discovery script and an end-to-end paid call.
