## Which one, for what

### Apollo API + MCP (B)

Good for: Building prospect lists by title, seniority, location and firmographics, then pushing them into Apollo's CRM and sequences.

Ahead on:
- Reliability, 65 against 40
- Schema & documentation, 87 against 72
- Agent ergonomics, 65 against 57
- Security & auth, 60 against 45
- Maintenance & community, 58 against 35

### Fuse MCP (D)

Good for: Suited to a salesperson or founder who wants an assistant to build prospect lists, enrich them and run email and LinkedIn outreach inside one Fuse account.

Watch for: The only OAuth scope is `mcp:tools`, so a connection can do everything its user can, including sending email and LinkedIn messages

## 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
