Keys have no scopes, the Claude Code plugin auto-approves most CLI calls, and the privacy policy dates from 2020.\n\n**FullEnrich API + MCP.** Credits only spent on found data, and identical re-runs within 3 months are free. Enrichment sources are third-party providers the vendor doesn't name.\n\n## Before you call either\n\n### Clay\n\n1. Fetch GET /search/query-mode/reference before writing a search query\n2. Poll routine results until a terminal 200, since 202 means still running\n3. Expect HTTP 402 when a plan's search cap is hit, and tell the user the reset date\n4. Check GET /credits/balance before large batch runs\n5. Ask the user before enabling the plugin's auto-approve hook in a shared workspace\n\n### FullEnrich API + MCP\n\n1. Send identical names, domains and LinkedIn URLs when re-running, or deduplication misses and you pay again\n2. Expect 30 to 90 seconds a contact. Use the webhook or poll `get_enrichment_results`\n3. Ask for mobiles only when needed. They cost 10 credits against 1 for a work email\n4. Call `list_industries` and `list_seniorities` before filtering search\n5. Use the 0-credit test contacts in the docs to check an integration\n\n## Questions\n\n### Which is better for AI agents, Clay or FullEnrich API + MCP?\n\nFullEnrich API + MCP scores 59.6 (C) on agent readiness against Clay's 57.7 (C), and leads in 3 of 7 scored categories. Clay leads on schema \u0026 documentation, agent ergonomics and maintenance \u0026 community.\n\n### Do Clay and FullEnrich API + MCP need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Clay and FullEnrich API + MCP without installing anything?\n\nYes.
