Enrichment sources are third-party providers the vendor doesn't name.\n\n**Fuse MCP.** The server documents 290 tools with read-only and destructive annotations, OAuth with PKCE and dynamic client registration, and published limits of 60 requests a minute. The single `mcp:tools` scope grants everything the user can do, sends happen at once with no undo, and no status page, changelog or security contact was found.\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### Fuse MCP\n\n1. Keep the client's approval prompt on for every tool that is not read-only. Sends, CRM pushes and Slack posts run at once with no undo\n2. Launch a campaign only on an explicit request. Creating one makes a draft, and `update_campaign_status_tool` starts real outreach\n3. Call `get_credits_balance` and `get_credit_prices` first. Every call needs at least 100 credits, and searches cost 2 credits a result\n4. Resolve filter values with `lookup_filter_values` or `get_company_search_enums` before `search_people` or `search_companies`\n5. Start long work with `deep_research_start`, then poll `deep_research_status`. A tool call has 60 seconds, and runs take 5 to 20 minutes\n\n## Questions\n\n### Which is better for AI agents, FullEnrich API + MCP or Fuse MCP?\n\nFullEnrich API + MCP scores 59.6 (C) on agent readiness against Fuse MCP's 47.9 (D), and leads in 6 of 7 scored categories.\n\n### Do FullEnrich API + MCP and Fuse MCP need an API key?\n\nFullEnrich API + MCP takes an API key or an OAuth sign-in. Fuse MCP uses an OAuth sign-in.\n\n### Can an agent call FullEnrich API + MCP and Fuse MCP without installing anything?\n\nYes.
