Dev Tools MCP Server

An MCP server with a small catalog of developer CLI tools; "install" and "check" read and write a JSON file and do not touch the system.

packages/dev-tools-mcp

This package is an MCP server plus a console window. The idea is that an agent can ask what tooling a machine has and request more. The current code keeps a catalog file and nothing more.

robos_devtools_install sets installed: true on a catalog entry and replies “Successfully provisioned”. It does not download or run anything. robos_devtools_check reports the flag in the file, not whether the binary is on your PATH.

Tools and resources

Tool What it does
robos_devtools_list Returns the whole catalog with each entry’s installed flag and version
robos_devtools_check Looks up one tool id; reports “not in the RobOS tool catalog” for unknown ids
robos_devtools_install Marks a tool installed. An unknown id is added as a “Custom CLI” entry at version 1.0.0
robos_devtools_uninstall Marks a tool not installed; errors on an unknown id

Resources: robos://dev-tools-mcp/devtools/installed and robos://dev-tools-mcp/devtools/available.

The default catalog has Docker Engine, Kubernetes CLI (kubectl), GitHub CLI (gh), K9s, HashiCorp Terraform and AWS CLI v2. Docker, kubectl, gh and K9s start as installed, with the version numbers written in server.js.

Console window

The window title is “RobOS Dev Tools MCP Server Console”. It shows counters (installed, catalog size, tools, pending), the tool registry, quick buttons (Check Docker, Install Terraform) and a Live Dev Tools MCP Protocol Trace with Clear Trace. It calls the service over Electron IPC.

Data and registration

  • Catalog: ~/.config/robos/devtools/tools.json, written on first run.
  • On start the server records its tool and resource names in ~/.config/robos/mcp/servers.json under the id devtools. It opens no port unless a port option is passed.
electron packages/dev-tools-mcp
