Add my server

Install Proton Workflow Connector in Claude Code

What you need first

  • Claude Code, installed.
  • uv, which gives the uvx command the server starts with.
  • Your own values for YOUR_PROTON_BRIDGE_USERNAME,YOUR_PROTON_BRIDGE_PASSWORD,YOUR_PROTON_BRIDGE_EMAIL.

Steps

  1. Run this in a terminal, in the project folder. It adds the server for you in that project; put --scope user after claude mcp add to have it in every project.
claude mcp add --env PROTON_BRIDGE_USERNAME=YOUR_PROTON_BRIDGE_USERNAME --env PROTON_BRIDGE_PASSWORD=YOUR_PROTON_BRIDGE_PASSWORD --env PROTON_BRIDGE_EMAIL=YOUR_PROTON_BRIDGE_EMAIL --transport stdio proton-workflow-connector -- uvx proton-workflow-connector==1.3.0
  1. Replace YOUR_PROTON_BRIDGE_USERNAME,YOUR_PROTON_BRIDGE_PASSWORD,YOUR_PROTON_BRIDGE_EMAIL with your own values.
  2. Start Claude Code and type /mcp: the server is listed with its state.

Check it worked

Ask Claude Code: List the tools of proton-workflow-connector.

If it does not start

spawn uvx ENOENT
uv is not on the PATH that Claude Code sees. Install it, or write the full path of uvx in the config.
The server starts, but its tools fail
A YOUR_… placeholder is still in the config, or its value is wrong.
