Supabase
Supabase’s official server lets AI create tables, query data and review project settings in your Supabase database.
Description from the maker (original English)
cc0pedia CC0 database + cc0.company agent services as MCP tools, paid per call via x402 on Base.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
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.
The registry does not list a required key, though some servers ask you to sign in on first use.
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.
The GitHub repo last changed –, and the latest version (2.0.0) reached the registry 4 months ago.
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.

MongoDB Model Context Protocol Server
MCP server for interacting with Elasticsearch
Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.
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.
A remote MCP server that turns cc0.company's managed agent services into tools any AI agent can call:
Tools are discovered live from the catalog (tools/list), so the set grows over time without changing your client.
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.
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" } } }

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