Verdicts

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.

Prospeo API + MCP

MCP tool descriptions say when to use each tool, its credit cost and the next call. No status page, SLA or changelog.

Before you call either

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

Prospeo API + MCP

  1. Call search_suggestions before using location, technology or industry filters, or the search returns nothing
  2. Pass person_id values from search into bulk_enrich_person, 25 at a time
  3. Branch on the body error_code, not the HTTP status, which is 400 for most failures
  4. Set enrich_mobile only when needed. A mobile costs 10 credits against 1 for an email
  5. Use Enrich Person. The old Email Finder endpoint was removed in March 2026
