MCP server · Agent Zero

agent-zero-intel

Agent Zero operates a free, anonymous remote MCP server at https://api.onchainagentintel.io/mcp (Streamable HTTP; a GET or a POST without Accept text/event-stream returns 406 -32600 "Client must accept text/event-stream"). initialize answered with protocolVersion 2025-06-18 and serverInfo agent-zero-intel 1.8.0; tools/list returned four read-only tools with real inputSchema, saved verbatim to onchainagentintel-io-mcp-tools.json; prompts/list and resources/list both return empty arrays. Every tool response carries an `unlock`/`upgrade` block pointing at the paid x402 /v1/intel/* REST endpoint. The server is advertised in the agent card (x-mcp-servers), the root manifest (/agent.json mcpServers[]) and the OpenAPI (POST /mcp, operationId public_mcp_post).

Connect

This is a remote MCP server — point an MCP client at the endpoint URL. Clients with native remote support (Claude, Cursor, VS Code, …):

# mcp client config (e.g. .mcp.json / mcp settings) { "mcpServers": { "onchainagentintel-io": { "url": "https://api.onchainagentintel.io/mcp" } } }

For stdio-only clients (older Claude Desktop, etc.), bridge with mcp-remote:

# Add to claude_desktop_config.json { "mcpServers": { "onchainagentintel-io": { "command": "npx", "args": ["-y", "mcp-remote", "https://api.onchainagentintel.io/mcp"] } } }

If the server requires authentication, add the provider's token/header (e.g. an X-API-Key) per its docs. A quick reachability check:

curl -i -X POST https://api.onchainagentintel.io/mcp \ -H "Content-Type: application/json" -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

get_leaderboards — Top ERC-8004 agents by live MCP tool count, by OpenAPI method count, and most recently indexed — names and counts only. Paid counterpart GET /v1/intel/trending.
get_agent_summary — Objective, counts-only signals for one ERC-8004 agent. Paid counterpart GET /v1/intel/agent/{agent_id}.
get_network_teaser — A capped teaser of the on-chain agent-to-agent payment graph (nodes + edges). Paid counterpart GET /v1/intel/graph.

About MCP

The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.

Work with this as data

Every MCP server here is available over the APIs.io API and to AI agents over MCP.
