Probes a domain for known AI agent integration signals: `llms.txt`, `ai.txt`,
`/.well-known/ai-plugin.json`, `openapi.json`, `swagger.json`, MCP manifest, MCP
SSE endpoint. Returns a score based on the count of signals detected. Use this to
assess whether a domain is ready for agent-to-agent interaction.
Use this tool when:
- You want to know whether a domain exposes an MCP server or OpenAPI spec for agents.
- You are cataloguing the AI-agent-ready surface of a set of domains.
- You need to decide whether to attempt programmatic API access to a domain.
Do NOT use this tool when:
- You need tracker/surveillance data about the domain — use `get_domain` instead.
- You need the robots.txt AI crawler policy — use `intel_robots` instead.
- You need HTTP security posture — use `intel_http` instead.
Inputs:
- `domain` (query, required): Domain to probe.
Returns:
- Boolean flags per signal (`llms_txt`, `ai_plugin`, `openapi`, `mcp_manifest`,
`mcp_endpoint`, `mcp_sse`).
- `agent_surface_score`: integer 0-8, count of signals detected.
Cost:
- Free. No API key required.
Latency:
- Typical: 2-5s (parallel probes), p99: 8s.
