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.

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.
| Protocol | x402 v2 |
| Network | Base mainnet — eip155:8453 |
| Asset | USDC — 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 |
| Scheme | exact (fixed price per call) |
| Facilitator | Coinbase CDP |
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.
Tools
Discovered dynamically — tools/list is the source of truth. At launch:
| Tool | Price | What it does |
|---|---|---|
cc0pedia | $0.01 | Resolve one CC0 creator/collection/work by name or slug → provenance, license, on-chain pointers, full CC0 body |
cc0pedia-search | $0.01 | Ranked free-text search across the CC0 database |
cc0pedia-verify | $0.01 | License oracle — is a contract a documented CC0 work? + full provenance |
cc0pedia-market | $0.01 | Live market for a CC0 asset — token price/FDV/liquidity/volume, or NFT floor/volume/owners |
cc0-daily-brief | $0.05 | Hourly digest of the top CC0 NFT collections by 24h volume |
sartoshi-gen · darkfarms-gen · hokusai-gen · van-gogh-gen · monet-gen | $0.069 | CC0 image generation (async — returns a job_id to poll) |
mfergpt-ask · mfergpt-lore · mfergpt-mferfy | varies | Third-party mfergpt services, re-brokered over x402 |
