# IdentityConnectors > Evidence-first discovery of identity, authentication, authorization, credential and workload-identity infrastructure for AI agents and developers. ## Important semantics - Unknown support is not confirmed support. - /api/recommend is deterministic and evidence-based. - /api/ai-recommend uses an AI model only to compare the deterministic top-five verified candidates; it may not introduce outside vendors. - Verify provider capabilities against current provider documentation before implementation. ## Primary pages - https://identityconnectors.com/ - https://identityconnectors.com/for-agents - https://identityconnectors.com/machine-readable ## Machine endpoints - Catalog: https://identityconnectors.com/api/catalog.json - Full dataset: https://identityconnectors.com/identity-connectors.json - Structured recommendations: https://identityconnectors.com/api/recommend?q=YOUR_REQUIREMENT - AI comparison: https://identityconnectors.com/api/ai-recommend?q=YOUR_REQUIREMENT - ARD: https://identityconnectors.com/.well-known/ard.json - MCP metadata: https://identityconnectors.com/mcp.json - Health: https://identityconnectors.com/health ## Representative queries - My agent needs Gmail and Salesforce access on behalf of users, with OAuth tokens kept outside the model and MCP support. - Find identity infrastructure for delegated Microsoft 365 access plus workload identity. - I need fine-grained authorization for a RAG agent so users only retrieve documents they are allowed to see. - Which identity systems explicitly support AI-agent identity or MCP authorization?
