Claude and Claude Code MCP

Add the Proferex MCP server to Claude and Claude Code.

Add Proferex as a custom MCP connector in Claude on the web or desktop. Claude Code can use the same MCP connection, or you can add the MCP server in the terminal.

Add the Proferex MCP connector in Claude

  1. In Claude, open Settings → Connectors, click Add and choose Add custom connector.
  2. Enter Proferex as the name and paste this address as the URL:
https://www.proferex.com/api/mcp

Copy it exactly, including www. The address without www doesn't connect.

The Add custom connector dialog in Claude with the name Proferex and the URL https://www.proferex.com/api/mcp
Name the connector and paste the Proferex address
  1. Click Continue. Claude shows the sign-in settings it detected. Leave them as they are:
    • Authentication: Sign in now
    • OAuth client: Register automatically
    • Request headers: none
Claude sign-in settings with Sign in now and Register automatically selected, both marked Detected
Leave the detected settings and click Add
  1. Click Add, then Connect. Claude opens a Proferex page. Sign in if you are asked to.
  2. Proferex shows Connect Claude to Proferex?, what Claude will be able to do, and the account it will connect to. Check that it's your account, then click Allow access. You go back to Claude, which is now connected.
The Proferex page Connect Claude to Proferex? listing read access and proposing tracker changes, with Allow access and Deny buttons
Check the account, then click Allow access

Click Deny instead if you didn't start the connection or the account is wrong.

  1. Back in Settings → Connectors → Proferex, set Read-only tools to Always allow, so Claude doesn't stop to ask every time it looks up your stats. Leave Write/delete tools on Needs approval, so Claude checks with you before it proposes a change.

Ask Claude for a change

Claude asks before it sends a change. Click Allow once. The change then goes to Proferex for your approval. Nothing is created yet.

Add the Proferex MCP server in Claude Code

If you already connected Proferex in Claude on the web, Claude Code picks it up by itself when you sign in to Claude Code with the same Claude account. Type /mcp in Claude Code and look for claude.ai Proferex under claude.ai.

To add it to Claude Code on its own instead, run this in a terminal:

claude mcp add --transport http --scope user proferex https://www.proferex.com/api/mcp

--scope user makes Proferex available in every project. Leave it out to add it to the current project only.

Start Claude Code with claude and type /mcp. If proferex needs signing in, choose it and follow the prompt. Your browser opens the Proferex page, asking Connect Claude Code to Proferex? Click Allow access, then go back to the terminal.

Use one or the other. If both are set up, Claude Code uses the one you added in the terminal and hides claude.ai Proferex.
