Verdicts

Crustdata API + MCP

Per-field credit prices, readable per account from /account/endpoints, and X-Credits-Used on every response. No status page and no SLA.

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.

Before you call either

Crustdata API + MCP

  1. Always send x-api-version: 2025-11-01. Unpinned calls get the latest version
  2. Call /account/endpoints first to see what your plan enables and what each field costs
  3. Ask only for the premium field groups you need, since each one bills
  4. Poll GET /batch/{id} before submitting more batch jobs. Active jobs count against a cap of 5 to 30
  5. Read the crustdata://catalog resource before calling MCP tools

Fuse MCP

  1. 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
  2. Launch a campaign only on an explicit request. Creating one makes a draft, and update_campaign_status_tool starts real outreach
  3. Call get_credits_balance and get_credit_prices first. Every call needs at least 100 credits, and searches cost 2 credits a result
  4. Resolve filter values with lookup_filter_values or get_company_search_enums before search_people or search_companies
  5. 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
