No status page and no SLA.\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### Crustdata API + MCP\n\n1. Always send `x-api-version: 2025-11-01`. Unpinned calls get the latest version\n2. Call `/account/endpoints` first to see what your plan enables and what each field costs\n3. Ask only for the premium field groups you need, since each one bills\n4. Poll `GET /batch/{id}` before submitting more batch jobs. Active jobs count against a cap of 5 to 30\n5. Read the `crustdata://catalog` resource before calling MCP tools\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, Crustdata API + MCP or Fuse MCP?\n\nCrustdata API + MCP scores 53.4 (D) on agent readiness against Fuse MCP's 47.9 (D), and leads in 6 of 7 scored categories. Fuse MCP leads on payments \u0026 pricing.\n\n### Do Crustdata API + MCP and Fuse MCP need an API key?\n\nCrustdata API + MCP takes an API key or an OAuth sign-in.
