With the fynk MCP server, you can work with fynk from the AI assistant you already use. Create documents, search contracts, update fields or add signatories by asking in plain language.

Available on Essential, Business and Pro · Each user connects their own assistant

Before you start

  • An Owner must turn on Enable MCP for this organization in Account settings → MCP. The View documentation button there opens the MCP documentation.
  • After that, every user can connect their own AI tool. Permissions follow fynk: AI tools can only access what each user can already see and do in fynk. No new permissions are created or required.
  • The server URL is the same for every AI tool: https://app.fynk.com/mcp
  • Account settings → MCP lists the supported AI tools at the bottom, each with a setup guide.
  • Adding a custom connector may need admin rights in the AI tool itself, for example a Claude admin, a ChatGPT admin with Developer Mode, or a Cursor admin.

Claude

  1. In Claude, go to Settings → Connectors and click Add custom connector.
  2. Enter the name "fynk" and the URL https://app.fynk.com/mcp, then click Add.
  3. Click Connect, log in to fynk and approve the connection.

To upload PDFs to fynk from Claude, turn on network access in Claude's capability settings.

Claude Code

  1. Run claude mcp add --transport http fynk https://app.fynk.com/mcp.
  2. Start Claude Code, run /mcp, select fynk and click Authenticate.
  3. In fynk, confirm the localhost address with I recognize and trust this URL, then click Approve.

If the authentication URL doesn't open automatically, copy it from the terminal into your browser. The localhost prompt is expected, because Claude Code runs on your computer.

ChatGPT

  1. In ChatGPT settings, go to Apps. If you're adding your first custom connector, turn on Developer Mode under advanced settings.
  2. Click Create app, enter the name "fynk" and the server URL, and choose OAuth as authentication.
  3. Click Sign in with fynk and approve the connection.

Cursor and other tools

In Cursor, go to Settings → Cursor Settings → Installed MCP Servers → Add Custom MCP and enter the name and URL. In any other MCP-compatible tool, add the server URL and approve the connection in fynk.

What you can ask

  • Create an NDA from our standard template for Demo Inc.
  • Show me all active supply agreements tagged "Sales".
  • Which contracts need to be signed this week?
  • Add John Doe as a signatory and start the signing process.
  • Set the contract term to 24 months.
  • Upload this PDF and mark it as completed.
  • Archive the contract with Demo Inc.
  • Who has access to this document?
  • List our templates, document types and metadata fields.

Manage connections as an admin

In Account settings → MCP you can see all connected AI tools and who connected them, disconnect individual tools, and choose to notify Owners and Admins when someone connects a new tool.

Good to know

  • Once data reaches your AI tool, its provider decides where it's processed. For guaranteed processing in the EU, use the fynk AI Assistant.
  • Not yet possible via MCP: creating share links, starting approval workflows, and creating metadata fields.
  • Some actions via MCP use AI credits, for example starting an AI analysis.
  • Each person using MCP needs a fynk user licence.
