Claude, or another AI app, can open, change and run your projects with you, through BBRouter’s MCP server. Connect it once: it asks you to sign in, then works as you, on your projects only.

MCP server address

https://bbrouter.com/api/mcpCopy

Claude Code

claude mcp add --transport http bbrouter https://bbrouter.com/api/mcpCopy

Then type /mcp in Claude Code, pick bbrouter and choose Authenticate to sign in.

Settings → Connectors → Add custom connector: name it BBRouter, paste the address and click Add, then Connect and sign in.

Other apps

Any app that takes a remote MCP server (HTTP, with OAuth sign-in): give it the address.
