Overview

Description from the maker (original English)

cc0pedia CC0 database + cc0.company agent services as MCP tools, paid per call via x402 on Base.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Databases & datasets

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

Common questions

Is Cc0company MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.0.0) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

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

claude mcp add --transport http cc0pedia https://cc0.company/api/mcp

Cursor — .cursor/mcp.json

{ "mcpServers": { "cc0pedia": { "url": "https://cc0.company/api/mcp" } } }

Claude Desktop / claude.ai — Settings → Connectors → *Add custom connector* → 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.

Protocolx402 v2
NetworkBase mainnet — eip155:8453

Schemeexact (fixed price per call)
FacilitatorCoinbase 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.
