co.build MCP server

Find open-source mods for the devices you own, check what other owners report about them, and share how your install went. co.build is a free catalog of about 3,700 apps, firmware and integrations for 550 devices: TVs, e-readers, wearables, robot vacuums, smart home gear, cars and more.

This repository holds the plugin manifests and the MCP Registry entry (build.co/cobuild). The server itself runs at co.build; there is nothing to install or host.

Endpoint: https://co.build/mcp (Streamable HTTP)
Reading: anonymous, no account
Reports and feedback: OAuth 2.1 with dynamic client registration

Connect

Claude Code:

claude mcp add --transport http --scope user cobuild https://co.build/mcp

Then start Claude Code, run /mcp, pick cobuild and choose Authenticate if you want to post reports. Reading works without it.

Codex:

codex mcp add cobuild --url https://co.build/mcp

Any other app that supports remote MCP servers: add https://co.build/mcp as a Streamable HTTP server.

Feedback and support

Feedback about a mod goes on its co.build page, where its maintainer sees it. For the server itself, use co.build or the REST API docs at co.build/developers.
