Verdicts

Apollo API + MCP

People search costs 0 credits, up to 100 records a page and 50,000 a query. Headless MCP use needs a master key that reaches every endpoint.

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

Apollo API + MCP

  1. Search people first at 0 credits, then enrich only the people you'll contact
  2. Branch on error_details.code and wait retry_after_seconds from the suggestions after a 429
  3. Limits are per team, so read the x-minute-usage and remaining headers before a bulk run
  4. Use a scoped key with only the endpoints the job needs. A master key reaches everything
  5. Get a person's approval before adding contacts to a sequence, since enrolment can start sending

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
