Connect an MCP client

Add the Locus MCP server to the chat or coding app you already use, then approve it in your browser. Use this when you work with the agent yourself. For an agent that runs unattended, use an agent key instead.

How it works

Your client starts a standard OAuth sign-in. Locus shows you a consent screen, you approve, and the client receives a token it stores and refreshes on its own. You never paste a key.

The consent screen shows the workspace and the access the client asks for.
If your workspace has tool sets, you choose the set this connection uses.
Signed-in clients appear under Connect → API keys in Connected apps.

Set up your client

In your workspace, Connect → Set up walks you through each client. You can also follow the steps below. Want the skills too? The Locus plugin installs the connection and skills together. You only need one connection.

Open Customize → Connectors → Yours → Add connector → Add custom connector. Name it Locus, enter the MCP server URL above, choose Connect, and complete browser sign-in.Then open Customize → Skills → Yours → Add skill → Upload skill and upload all three archives:

Claude Code uses the plugin instead.

Enable Developer mode under Settings → Apps → Advanced settings, then open Plugins → Create app. Enter the MCP server URL above, choose OAuth, and finish Locus sign-in. Start a Work task, open Plugins, and select Locus Pro before asking it to use a tool.ChatGPT’s Skills picker may not accept the skill archives. The MCP app still works; your agent can call get_locus_guide for the same guides.

claude mcp add --transport http locus-pro \
  https://api.paywithlocus.com/api/credits/mcp

Run /mcp, select locus-pro, and choose Authenticate.

codex mcp add locus-pro --url https://api.paywithlocus.com/api/credits/mcp
codex mcp login locus-pro --scopes mcp:read,mcp:execute,offline_access

This adds the MCP tools only. Install the Codex plugin to add the skills as well.

Add this to ~/.cursor/mcp.json, enable the server, and follow the OAuth prompt:

~/.cursor/mcp.json

{
  "mcpServers": {
    "locus-pro": {
      "url": "https://api.paywithlocus.com/api/credits/mcp"
    }
  }
}

cline mcp install locus --transport http \
  https://api.paywithlocus.com/api/credits/mcp

Choose Remote (HTTP) and OAuth, leave the client ID blank, and complete browser sign-in. Then install the skills and start a new Cline session:

npx skills add locus-technologies/locus-pro-plugin

Select locus, locus-setup, and locus-workflows when prompted.

The Locus CLI can print a ready-to-paste configuration for several clients with locus mcp config --client <name>.
