Connecting to the Pylon MCP Server

Last updated: April 22, 2026

The Pylon MCP server at https://mcp.usepylon.com provides AI tools access to your Pylon data. It uses OAuth authentication with your Pylon account.

The application you connect to Pylon's MCP will only have access to data you would have access to in Pylon, and will read and write on behalf of you.

Common Clients

Claude Code

claude mcp add pylon --transport http https://mcp.usepylon.com/

Then, in Claude Code, run the /mcp command and select the pylon MCP to authenticate.

Claude Desktop and Web

In "Admin Settings", add a custom connector named "Pylon" with URL https://mcp.usepylon.com/

Leave "OAuth Client ID" and "OAuth Client Secret" blank.

Navigate to "Settings > Connectors" and click the "Connect" button next to the Pylon MCP to authenticate.

In the Apps tab, search for Pylon and install our native ChatGPT app.

Cursor

Add to your Cursor MCP settings:

~/.cursor/mcp.json :

{
"mcpServers": {
...
"pylon": {
"url": "https://mcp.usepylon.com/"
}
...
}
}

Navigate to "Cursor Settings > Tools & MCP" and click "Connect" next to the Pylon MCP to authenticate.

Authentication Flow

Note: The Pylon MCP server only supports OAuth authentication. API key authentication is not currently available, which may affect usage in remote environments or platforms that don't support OAuth for remote connections.

1. When the MCP client connects, it will open your browser

2. Log in with your Pylon account credentials

3. Authorize the MCP connection

4. The browser will redirect back and complete the OAuth flow

5. Your MCP client is now connected to Pylon!

Session Expiry and Reconnecting

OAuth sessions expire periodically. The exact duration varies by MCP client - some sessions last a few hours, others can last several days.

When your session expires, you may see authentication errors or your MCP tools may stop returning results. To reconnect, simply re-authenticate through the same flow you used during initial setup:

  • Claude Code: Run /mcp and re-authenticate the Pylon connection

  • Claude Desktop/Web: Go to Settings > Connectors and click "Connect" next to Pylon

  • Cursor: Go to Cursor Settings > Tools & MCP and click "Connect" next to Pylon

This is normal behavior and not a bug. If you find yourself needing to reconnect unusually frequently (e.g. multiple times per day), please reach out to support.

Available Tools

Once connected, your MCP client will have access to the Pylon tools listed on this page: https://docs.usepylon.com/pylon-docs/integrations/mcp

Use case examples

  • Debug an issue end to end: Solve an issue with Claude Code with a prompt like "debug this <pylon link>" and put up a PR for a bug fix

  • Write a product spec notion doc: Feed it a bunch of issues and use a Claude Code skill to generate a product spec doc based on evidence

  • Ad hoc analysis: Ask a question about a customer in ChatGPT and leverage data from Pylon in addition to other tools like Notion or Linear

Seat requirement: You need a Member or Admin seat to connect to the MCP server. Viewer and Integration users cannot authenticate and will see an "Authorization failed" error. If you hit this, ask your workspace admin to upgrade your seat type in Settings > Users.
