Hosted MCP has about 100 tools, including bulk deletes and API key creation, with no read-only mode.\n\n## Before you call either\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### Hunter API + MCP\n\n1. Treat 451 as final. The person opted out and retrying won't help\n2. Back off on 403 with a rate-limit message. 429 means the plan's credits are gone\n3. Send the key in `X-API-Key`, never as `?api_key=`\n4.
