Auth headers

Pass your key as the X-Agent-Identity header. All operations that have a cost require a valid key.

# Direct HTTP
POST https://hatchloop.dev/mcp/agent-broker
Content-Type: application/json
X-Agent-Identity: YOUR_KEY_HERE

# In MCP config
{
  "mcpServers": {
    "agentbroker": {
      "url": "https://hatchloop.dev/mcp/agent-broker",
      "headers": {
        "X-Agent-Identity": "YOUR_KEY_HERE"
      }
    }
  }
}

FAQ

Is the free key really free forever?
Yes. An email-verified free key costs nothing and is valid for 90 days; request a new one when it expires. You only pay if you need the write tools without the daily cap.
What is the rate limit on the free tier?
A free key allows 50 gated (write) operations per day. The 8 read tools, like find_business and verify_business, are free without any key. For unlimited writes, upgrade to the $9/90d plan.
Which MCP clients does AgentBroker work with?
Any MCP-compatible client: Claude Desktop, Cursor, Claude Code, or any custom agent that speaks the MCP JSON-RPC spec. Add the endpoint URL and key header to your config.
Does x402 work on mainnet yet?
Not yet. x402 micropayments are in testing on Base Sepolia testnet. We have one recorded settlement. Mainnet will be announced when it is measured and working.
Where do I get help?
Email hello@hatchloop.dev. We do not have a support SLA but we read every email.
