Verdicts

Enrich Layer API + MCP

Pay-as-you-go credits from $10, non-expiring unless idle for 18 months. Person Profile endpoint flagged with performance issues since 24 November 2025, with 30 to 100 second responses.

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

Enrich Layer API + MCP

  1. Top up once before testing. Trial keys run at 2 requests a minute
  2. Set the person profile timeout to at least 100 seconds
  3. Ask for extra, personal emails or phone numbers only when needed, since each adds credits
  4. Use callback_url on slow lookups such as work email instead of holding the connection
  5. Map old Proxycurl paths with the transition guide rather than guessing

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
