# Agent access — They Use AI

Agents may search and cite the same broad company signals shown on the website.

Read-only interfaces:
- GET https://theyuseai.com/api/registry?query=&category=&location=&limit=20
- GET https://theyuseai.com/api/firms/{slug}
- POST https://theyuseai.com/mcp (MCP Streamable HTTP, stateless JSON responses)
- Browser WebMCP tools: search_ai_company_registry, get_ai_company_profile

Rules for accurate use:
1. Grades use the fixed rules on the methodology page. They are not based on a curve.
2. A business marked Not yet rated does not have an AI grade; this is not a negative finding.
3. Cite only the grade or information status and broad signals returned by the public profile.
4. Exact tools, source links, claim details, confidence calculations, and internal scoring data are private.
5. Never infer that an individual professional uses AI from a firm-level signal.
6. Do not present this directory as a rating of service quality.

Corrections and profile claims use the form linked from each profile.
