Claude.ai Custom Connector

Give Claude direct access to your ABM.dev workspace. Enrich contacts, find people, run campaigns, and send the personalised messages you wrote — all through a conversation.

What it is

The ABM.dev Custom Connector is a Model Context Protocol (MCP) server that plugs into Claude.ai. Once installed, Claude can call your ABM.dev tools on your behalf — with your consent — to enrich contacts, run campaigns, draft outreach, and more.

It speaks the official MCP Authorization spec (2025-06-18): OAuth 2.1 with PKCE, Dynamic Client Registration, and audience-bound access tokens. No API keys to copy and paste. Just click "Add connector," sign in once, and Claude is wired to your workspace.

How it works

The connector lives at mcp.abm.dev. When Claude first connects, it runs through a one-time OAuth flow:

1.Claude.ai fetches our OAuth metadata and registers itself via Dynamic Client Registration.
2.You're redirected to abm.dev/sign-in to authenticate with Clerk.
3.You see a consent screen showing your email, workspace, and requested scopes. Click Allow.
4.Claude receives a short-lived access token bound to mcp.abm.dev. It can now call tools on your behalf.

No API keys to manage

You never need to copy, paste, or rotate an API key. Tokens expire in 1 hour, refresh automatically, and can be revoked at any time from your ABM.dev settings.
