Add the MCP to Claude Code
One command to let Claude Code, or your CI, push, list and download Test Nexus builds.
Claude Code can push, list and download Test Nexus builds without you leaving the editor.
Before you begin
- The Test Nexus MCP is a Model Context Protocol server: a small program an AI assistant can call to do real work.
- Claude Code installed and working.
- Node.js, which provides the npx command.
- A Test Nexus account, and a Remote Install project to push builds to.
Add the server
- Run: claude mcp add testnexus -- npx -y @twocan/testnexus-mcp
- Restart Claude Code so it picks up the new server.
Connect it to your account
- Ask Claude to list your builds. The server prompts for credentials the first time it needs them.
- Follow the prompt. Credentials are stored by the server, not pasted into your conversation.
What it can and cannot do
- It can push a build, list the builds in that project, and download one back.
- It cannot read your source, touch a device, or reach any other project.
- Rotate the key from Project Settings in the app and the previous one stops working. Keys also expire on their own after 90 days.
- Credentials are held by the server in your MCP client's own configuration, not typed into a conversation.
Why you can trust the package
- The source is public and Apache-2.0, so you can read what the three tools do before running them.
- It is published with signed provenance: npm records that the package was built and published by CI from that repository rather than uploaded from a laptop.
Use it from CI as well
- The same server answers a pipeline step; nothing about it assumes a human is typing.
Verify the result
- Ask Claude Code to list your Test Nexus builds. If it returns your projects, the server is connected. If it reports that no tool is available, Claude Code has not been restarted since the install.
