# 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
**Claude Code**
```bash
claude mcp add --transport http cc0pedia https://cc0.company/api/mcp
```
**Cursor** — `.cursor/mcp.json`
```json
{ "mcpServers": { "cc0pedia": { "url": "https://cc0.company/api/mcp" } } }
```

**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/`](./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 |
## Quick check (free)

curl -s https://cc0.company/api/mcp \
-X POST -H 'content-type: application/json' \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}' \
| jq '.result.tools[].name'
