Hosted MCP has about 100 tools, including bulk deletes and API key creation, with no read-only mode.\n\n**Lusha API + MCP.** API key on every plan, including Free with 40 credits a month. At least 1 credit per request even when nothing matches.\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### Lusha API + MCP\n\n1. Batch up to 25 contacts a request. A single bulk request costs 1 credit, not 1 per contact\n2. Ask for phones only when needed. A phone is 5 credits against 1 for an email\n3. Use the Buying Group endpoint. Decision Makers was retired on 2026-09-04\n4. Use `/v3/lookalike/contacts` for contact lookalikes\n5. Back off exponentially on 429. Free keys stop at 100 requests a day\n\n## Other comparisons with Hunter API + MCP or Lusha API + MCP\n\n- [Apollo API + MCP vs Hunter API + MCP](https://www.anchorterminal.com/compare/apollo-vs-hunter.md)\n- [Apollo API + MCP vs Lusha API + MCP](https://www.anchorterminal.com/compare/apollo-vs-lusha.md)\n- [Coresignal API + MCP vs Hunter API + MCP](https://www.anchorterminal.com/compare/coresignal-vs-hunter.md)\n- [Coresignal API + MCP vs Lusha API + MCP](https://www.anchorterminal.com/compare/coresignal-vs-lusha.md)\n- [Crustdata API + MCP vs Hunter API + MCP](https://www.anchorterminal.com/compare/crustdata-vs-hunter.md)\n- [Crustdata API + MCP vs Lusha API + MCP](https://www.anchorterminal.com/compare/crustdata-vs-lusha.md)\n- [Enrich Layer API + MCP vs Hunter API + MCP](https://www.anchorterminal.com/compare/enrich-layer-vs-hunter.md)\n- [Enrich Layer API + MCP vs Lusha API + MCP](https://www.anchorterminal.com/compare/enrich-layer-vs-lusha.md)\n- [FullEnrich API + MCP vs Hunter API + MCP](https://www.anchorterminal.com/compare/fullenrich-vs-hunter.md)\n- [FullEnrich API + MCP vs Lusha API + MCP](https://www.anchorterminal.com/compare/fullenrich-vs-lusha.md)\n- [LeadMagic API + MCP vs Lusha API + MCP](https://www.anchorterminal.com/compare/leadmagic-vs-lusha.md)\n- [Lusha API + MCP vs Prospeo API + MCP](https://www.anchorterminal.com/compare/lusha-vs-prospeo.md)\n- [Dropcontact API + MCP vs Hunter API + MCP](https://www.anchorterminal.com/compare/dropcontact-vs-hunter.md)\n- [Dropcontact API + MCP vs Lusha API + MCP](https://www.anchorterminal.com/compare/dropcontact-vs-lusha.md)\n- [Hunter API + MCP vs LeadMagic API + MCP](https://www.anchorterminal.com/compare/hunter-vs-leadmagic.md)\n- [Hunter API + MCP vs Prospeo API + MCP](https://www.anchorterminal.com/compare/hunter-vs-prospeo.md)\n",
