## 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
