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.

LeadMagic API + MCP

RFC 9457 problem-details errors with request_id, and Retry-After on 429. No free tier or trial credits, plans from $99 a month.

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

LeadMagic API + MCP

  1. Call preview_cost before bulk work. It's free
  2. Read X-Credits-Remaining after each call instead of polling the balance
  3. Treat 402 as out of credits and wait out Retry-After on 429
  4. Keep credit-free search under 13,333 calls a day per account
  5. Retry unknown validations later. They cost nothing
