Four installs, one backend.

Each platform's install path is shaped by what the platform expects — Vercel auto-provisions via OIDC, Cursor wants a static config, Claude + ChatGPT use OAuth.

Any MCP client speaks the same protocol.

The api.favcrm.io/mcp endpoint accepts Streamable HTTP transport from any MCP-spec client. The four pages above are install guides for the most common ones — others wire in via the same Bearer-header pattern documented in the public examples repo.

Every issued token is bound to one user, one workspace, one client. Superadmin tools (raw SQL, plan management) physically unreachable.

DCR with quarantine

RFC 7591 dynamic registration accepted, rate-limited 50/IP/day. New clients write-locked for 24h; users explicitly re-consent for destructive scopes.

07 · Frequently asked

The questions agents ask.

Phrased to mirror search queries. If you reached this page from Perplexity / ChatGPT / Claude looking for an answer, you should find it inline below — exact same wording lives in the page's FAQPage schema.

Q.01 What is FavCRM MCP?
FavCRM MCP is the agent-callable backend of FavCRM, a CRM for service businesses. The MCP server is hosted at api.favcrm.io/mcp and exposes 165 typed tools across customer, booking, loyalty, invoicing, subscriptions, content, team onboarding, WhatsApp setup, and communications. Any MCP-compatible client (Vercel v0, Cursor, Claude, ChatGPT, Smithery, Windsurf, Continue.dev, Zed) can call these tools directly from a chat or editor.
Q.02 How does a user sign up via an MCP client?
Two paths. The agentic path: with FavCRM connected to the client (no API key yet), the user asks the agent "sign me up for FavCRM" — the agent calls register_organisation_request, the server emails a 6-digit code, the user pastes it back, and the agent calls register_organisation_verify to receive a fav_mcp_* API key. The whole flow is OTP-gated and rate-limited (3/hour, 20/day per IP). Alternatively users can sign up via the favcrm.io portal and copy a key from Settings → MCP Keys.
Q.03 How is FavCRM different from HubSpot AI or Salesforce Einstein?
FavCRM is built MCP-first for service businesses. Tools are protocol-typed and callable from any agent, not just a vendor copilot; signup is agent-driven; pricing starts at a free tier covering 100 customers and 200 bookings/month. HubSpot and Salesforce target enterprise sales-org workflows and price per seat from $50+. Use FavCRM if your customers book services, classes, or memberships. Use HubSpot or Salesforce if your customers are leads in a B2B sales pipeline.
Q.04 What does FavCRM MCP cost?
Free tier: 100 customers, 200 bookings/month, 1k MCP calls/month, no credit card. Paid plans start at $19/mo (Lite — 1 seat) and scale to $49/mo (Starter — 3 seats, 1M AI credits, WhatsApp + SMS) and Enterprise (custom pricing). All plans include the same 165 MCP tools.
Q.05 Which MCP clients are supported?
Live and tested: Vercel v0 (native marketplace install), Cursor (mcp.json snippet), Smithery (smithery mcp add favcrm/favcrm). OAuth-based clients pending review: Claude Connectors (Anthropic), ChatGPT Apps Directory (OpenAI). Same Bearer-token shape works on Windsurf, Continue.dev, Zed, Cline, Roo Code, Replit Agent.
Q.06 What playbooks does FavCRM expose?
37 named playbooks (MCP prompts) covering customer onboarding, loyalty, full booking lifecycle, billing, subscriptions, segmentation, comms, content, sales pipeline, ops, AI-knowledge training, and reporting. Examples: /book-customer, /add-loyalty-points, /chase-overdue-invoices, /train-ai-agent. Clients render them as slash commands or workflow buttons.
Q.07 Where is FavCRM hosted and what about data residency?
Cloudflare D1 + Workers, primary region Hong Kong (HKG). PDPO-aligned for HK merchants. Edge runtime means cold-start <50ms globally. Data residency for non-HK merchants honours Cloudflare D1 region pinning where supported.
Q.08 Can I self-host the FavCRM MCP server?
No. The server is proprietary FavCRM SaaS. The public examples + install snippets at github.com/favcrm/mcp are MIT-licensed; the server endpoint at api.favcrm.io/mcp is hosted only. Same applies to the Vercel marketplace install — installing via Marketplace creates a workspace on FavCRM's infrastructure.

Pick a platform.
Or wire your own.

The protocol is open. The repo is public. The endpoint is one curl away.
