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.\n\n**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.\n\n## Before you call either\n\n### Fuse MCP\n\n1. 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\n2. Launch a campaign only on an explicit request. Creating one makes a draft, and `update_campaign_status_tool` starts real outreach\n3. Call `get_credits_balance` and `get_credit_prices` first. Every call needs at least 100 credits, and searches cost 2 credits a result\n4. Resolve filter values with `lookup_filter_values` or `get_company_search_enums` before `search_people` or `search_companies`\n5. 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\n\n### LeadMagic API + MCP\n\n1. Call `preview_cost` before bulk work. It's free\n2. Read `X-Credits-Remaining` after each call instead of polling the balance\n3. Treat 402 as out of credits and wait out Retry-After on 429\n4. Keep credit-free search under 13,333 calls a day per account\n5. Retry `unknown` validations later. They cost nothing\n\n## Questions\n\n### Which is better for AI agents, Fuse MCP or LeadMagic API + MCP?\n\nLeadMagic API + MCP scores 60.2 (C) on agent readiness against Fuse MCP's 47.9 (D), and leads in 6 of 7 scored categories. Fuse MCP leads on payments \u0026 pricing.\n\n### Do Fuse MCP and LeadMagic API + MCP need an API key?\n\nFuse MCP uses an OAuth sign-in. LeadMagic API + MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call Fuse MCP and LeadMagic API + MCP without installing anything?\n\nYes.
