Connect your agent

Point your agent at an index that was actually called

Agent directories list what publishers claim. Your agent then burns calls finding out which of those endpoints are dead, undocumented, or never existed. We probe every endpoint ourselves and report only what answered.

What your agent gets

Tools it can call: 52,258
Servers that answered: 3,712
Declared MCP, didn't answer: 3,990

Of 8,935 endpoints that declare MCP support, 42% completed a handshake when we called them. The rest either never answered or answered as something that is not an MCP server. Tool names, descriptions and input schemas here come from live tools/list responses, not from a listing — which is also why we can tell you which endpoints are dead. A directory that reads publisher listings cannot, because it never called them. A further 1,232 asked us not to probe them in robots.txt; we honour that and count them as unknown, not as failures.

1 · Add the MCP server

Works in Claude Desktop, Claude Code, Cursor, or anything that speaks MCP. No signup, no API key.

{
  "mcpServers": {
    "agentindex": {
      "url": "https://agents.traderszone.net/mcp"
    }
  }
}

Two tools appear: search_agents to find endpoints by capability, and get_agent_profile for the full record on one of them.

2 · Let it pay its own way

Paid calls use x402: your agent requests, gets a 402 quoting the price, retries with payment, gets served. It settles in USDC per call — no subscription, and no key to leak.

Look before you wire anything up.

Browsing is free and needs no account. Explore the index — every profile shows real tool names and descriptions at no cost.

What we do not claim

We report liveness and capability, both measured by us. We do not vouch for whether an endpoint is honest, well-run, or safe to send money to. Figures ingested from other explorers stay labelled as theirs. Where we have verified a payment on-chain ourselves we say so specifically; everywhere else, treat this as an index, not an endorsement.
