Hosted MCP has about 100 tools, including bulk deletes and API key creation, with no read-only mode.\n\n**RocketReach API.** The hosted MCP server has nine documented tools, OAuth 2.1 with dynamic client registration and machine-readable error codes, and searches cost no credits. Plan prices were not readable, the docs send API plan requests to email, the terms require a human account holder, and the `account` tool returns the account's API key to the model.\n\n## Before you call either\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. Use `test-api-key` to check request shapes without spending credits\n5. Use the hosted MCP at mcp.hunter.io/mcp, not the deprecated local npm package\n\n### RocketReach API\n\n1. Search first with `person_search` or `company_search`, which cost no credits, then look up only the profile IDs needed\n2. Treat `status: \"pending\"` as normal. Poll `check_person_status` after at least 3 seconds, and polling is free\n3. Do not echo the `account` tool's output to users or logs. It includes the account's API key\n4. Send the key in the `Api-Key` header. The `api_key` query parameter is deprecated\n5. Bulk lookup takes 1 to 100 queries and needs a webhook. Results arrive at the webhook, signed in `X-RocketReach-Signature`\n6. Do not loop on `unknown` from `email_verify`, or on `lookup_failed` and `not_found`. The last two are terminal\n\n## Questions\n\n### Which is better for AI agents, Hunter API + MCP or RocketReach API?\n\nHunter API + MCP scores 56.5 (C) on agent readiness against RocketReach API's 51.2 (D), and leads in 4 of 7 scored categories. RocketReach API leads on reliability and agent ergonomics.\n\n### Do Hunter API + MCP and RocketReach API need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Hunter API + MCP and RocketReach API without installing anything?\n\nYes. Hunter API + MCP has a hosted endpoint at https://api.hunter.io/v2 and RocketReach API at https://api.rocketreach.co/api/v2.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/hunter-vs-rocketreach.json, and with the fewest tokens: https://www.anchorterminal.com/compare/hunter-vs-rocketreach.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"hunter\", \"b\": \"rocketreach\"}`.
