API and MCP access are restricted to the Scale, Advanced and Enterprise tiers; lower tiers cannot use it at all. Launched in beta in 2026 with roughly 33 read and write tools. TRANSFERABILITY CAVEAT: Affinity is aimed at VC, PE and investment banking rather than classic B2B SaaS sales, so the relationship-strength model is tuned for a different motion than most of this directory. Included because the auto-built relationship graph is the same job Centralize (05) and The Swarm (01) do, approached from a third direction, and the three together are a coherent lane. 2026-09-07: https://mcp.affinity.co/mcp returned 401 to an MCP initialize POST (https://mcp.affinity.co/mcp). ## Named capabilities Tool names below are reported by sources.
