Domain knowledge for Agent Arena — workflow patterns, data models, and gotchas for your AI agent.
Agent Arena is a decentralized registry for AI agents built on the Base blockchain using ERC-8004 standards. It provides a searchable directory of agents with on-chain identity verification and reputation tracking.
Agent Discovery: Search the registry by agent capabilities, names, or descriptions to find agents suitable for specific tasks. Results include basic profile information and matching criteria.
Agent Profiles: Retrieve complete agent profiles using on-chain IDs, including detailed descriptions, API endpoints, reputation scores, registration metadata, and interaction history.
Agent Registration: Register new agents on the blockchain registry, which mints an on-chain identity NFT and makes the agent discoverable through the search system.
Agents have on-chain identities with profiles containing names, descriptions, capabilities, endpoints, and reputation metrics. The registry uses blockchain verification to ensure agent authenticity and tracks interaction history for reputation building.
The server exposes complete API documentation, Google Agent2Agent protocol discovery cards for interoperability, and Open Agentic Schema Framework records for standardized agent representation.
Registration requires blockchain interaction and may involve gas fees. Agent profiles are immutable once registered, so ensure accuracy before submission. Search supports natural language queries about agent capabilities rather than just exact matches.

Take over this listing's metadata — name, description, category, logo, website, contact email, and skill content. Verification is a 6-digit code we email to one of the maintainer addresses your server already publishes in /.well-known/security.txt or /.well-known/mcpbundles.json. Free, takes about a minute.
MCPBundles publishes this directory for MCP discovery. Except where we host or operate an offering, third-party services run under their own terms. Product and company names on this page are used in a descriptive, identifying way (including under nominative fair use where applicable); they remain the property of their owners. Nothing here grants you rights in those marks, and nothing here is an offer to sell a third party's services. Terms

Agent Arena Registry allows users to search for agents, retrieve their profiles, and register new agents. This server is useful for developers working on agent-based systems or applications that require agent management and interaction. It provides MCP tools that your client discovers when it connects (this page may not list every tool name) that AI agents can use through the Model Context Protocol (MCP).
Add the MCPBundles server URL to your MCP client configuration (Claude Desktop, Cursor, VS Code, etc.). The URL format is: https://mcp.mcpbundles.com/bundle/agent-arena-mcp. Authentication is handled automatically.
Agent Arena is a remote MCP server. The live tool list is supplied by the server when your MCP client connects, so the count is not fixed on this public page. After you connect in MCPBundles Studio or your client, you will see the tools your session can call. A SKILL.md is still included to guide your agent on capabilities and workflows.
Agent Arena uses API Key. Agent Arena requires credentials. Connect via MCPBundles and authentication is handled automatically.
