Linq Business + Claude / ChatGPT
Linq Business (linq-business.com) is contact capture from Linq cards, badges, kiosks and events, with follow-ups and tags. It is a personal contact list, not a pipeline CRM, and it is not another vendor's Linq product. The MCP server uses a Bearer API key and requires the Business plan. It works in Claude Code, Claude Desktop (Node.js and mcp-remote), Cursor and VS Code. It does not work in ChatGPT connectors or claude.ai custom connectors, which are OAuth-only. This entry is vendor-documentation verification from Nov 9, 2026, not a live account test.

| Claude | Custom connector (paste URL) Claude Desktop and Claude Code only, not claude.ai. claude.ai custom connectors are OAuth-only, and this server uses a Bearer API key. Claude Code: claude mcp add --transport http linq https://app.linq-business.com/api/v1/mcp with an Authorization: Bearer header. Claude Desktop needs Node.js and mcp-remote under Settings > Developer > Edit Config. Cursor (Settings > MCP) and VS Code (MCP user configuration) use the same HTTP URL plus that header. |
| ChatGPT | Not supported Linq says ChatGPT connectors can't use this server yet. Those connectors sign in with OAuth, and Linq expects a Bearer API key (lq_live_...). |
| Setup type | Self-install (URL) |
| Read-only or read/write | Read/write The assistant can search and list your contacts, read a contact (notes, tags and form answers), add contacts to your active card, and update details, status, tags, notes and follow-up dates. It can see open follow-ups and list your events. It cannot delete contacts, send email or messages, see teammates' contacts, or change your card. Revoking the key stops it. This is the MCP assistant, not Linq's separate REST API. |
| Admin setup needed? | No You create a per-app key under Integrations > Connect your AI assistant. The key is shown once. You can have up to 10 keys, and each key is limited to 120 requests a minute. Revoke stops a key immediately. The docs don't describe a separate admin approval for the MCP connection. |
| Plan / requirements | Requires the Linq Business plan. If the account isn't on Business, the server returns plan_required. The same key works again if the account is on Business again. |
| MCP / connector URL | https://app.linq-business.com/api/v1/mcp (Bearer API key, lq_live_...) |
