Follow Up Boss, wired into Claude.
A hardened remote MCP server that exposes 20 Follow Up Boss CRM tools to Claude clients — search leads, log notes, draft SMS, move stages, and audit your pipeline conversationally. Built for a real team running a real book of business.
Compliance & Security
Production-grade by default.
Per-agent bearer auth
withMcpAuth gates every request. One token per agent for attribution.
Rate limiting
Per-agent token bucket cuts off runaway loops before they hit FUB.
DNC / opt-out guard
Code-blocks outreach to Not Interested · Bad Lead · Bad Phone Number · DNC tags.
Error sanitization
FUB error bodies never reach the client — generic status messages only.
429 retry / backoff
Honors Retry-After and X-RateLimit-Reset. Reads only — never replays writes.
Security headers
nosniff · DENY framing · strict CSP · HSTS · no-store on /api/*.
Registered FUB system
X-System / X-System-Key required in production for source attribution.
No PII persistence
Stateless serverless — ephemeral 5–10 min cache for users / smart lists only.
Tools exposed
20 tools, organized by intent.
Connect
