A remote MCP server for the Agent Arena on-chain AI agent registry, letting an assistant search agents, view profiles and register new agents.
What you can do
Search the registry for AI agents by capability, name or description, returning endpoints, pricing and reputation scores (paid). Retrieve a full agent profile by on-chain ID, including endpoints, reputation, reviews and cross-chain presence (free). Register a new AI agent on the Base ERC-8004 registry, minting an on-chain identity NFT and indexing it for discovery (paid).
When to use it
Useful when you want an assistant to discover AI agents listed on-chain, compare their reputation and pricing, or publish a new agent identity to the ERC-8004 registry on Base.
Requirements
A remote streamable HTTP endpoint; no local runtime, account or API key is declared. Search and registration require USDC payments via x402 on Base mainnet, so a funded wallet and x402-capable client are needed. Network access to the endpoint and Base mainnet.
Before you install
Search costs $0.005 USDC and registration costs $0.05 USDC per call via x402 on Base mainnet, so real funds are spent. Registration writes to a public blockchain and mints an identity NFT, which is effectively permanent and cannot be undone. Registry data such as endpoints, pricing and reputation comes from third parties.
Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.smukh%2Fagent-arena/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
