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.

Lusha API + MCP

API key on every plan, including Free with 40 credits a month. At least 1 credit per request even when nothing matches.

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

Lusha API + MCP

  1. Batch up to 25 contacts a request. A single bulk request costs 1 credit, not 1 per contact
  2. Ask for phones only when needed. A phone is 5 credits against 1 for an email
  3. Use the Buying Group endpoint. Decision Makers was retired on 2026-09-04
  4. Use /v3/lookalike/contacts for contact lookalikes
  5. Back off exponentially on 429. Free keys stop at 100 requests a day
