Getting started

0bridge is one MCP endpoint for all your AI tools. Connect a service once and Claude Code, Codex, Cursor, Gemini CLI, Claude and ChatGPT all use it, and your instructions, memory and session history go where you go, so no single vendor holds your context.

Open in ClaudeOpen in ChatGPT

Set up a machine#

npm install -g 0bridge
0b setup

0b setup signs you in (a one-time code, works over SSH too) and adds your 0bridge endpoint to every AI tool it finds. Restart the tools after.

Connect a service#

0b connect linear
0b connect slack --label acme

Or on the dashboard under Connections. A label names the account when you connect more than one of a service; tools are then called slack__acme__….

Use it from Claude or ChatGPT#

Add a custom connector with the URL https://0bridge.dev/mcp and sign in with your 0bridge account. Step by step: Claude and ChatGPT. Which clients work, and how well: Supported clients.

Set up a tool by hand#

When the CLI isn't an option, add the endpoint to each tool yourself and sign in from it.

  • Claude Code: claude mcp add --transport http 0bridge https://0bridge.dev/mcp, then run /mcp in Claude Code to sign in.
  • Codex: codex mcp add 0bridge --url https://0bridge.dev/mcp; if the sign-in doesn't open, codex mcp login 0bridge.
  • Cursor: add {"mcpServers": {"0bridge": {"url": "https://0bridge.dev/mcp"}}} to ~/.cursor/mcp.json, then sign in from Cursor's MCP settings.
