How to add Locus MCP to Cline

Setup, step by step

1. Step 1

   Create a Locus Pro account

   Sign up at paywithlocus.com/pro. The Free plan has no subscription. Paid calls use prepaid credits.

2. Step 2

   Install the MCP server

   Run the install command. In the wizard, choose Remote (HTTP), choose OAuth, and leave the client ID blank.

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

3. Step 3

   Approve Locus

   Cline opens Locus in your browser. Sign in and approve the connection.

4. Step 4

   Add the Locus skills

   Run this in your project folder. Select locus, locus-setup, and locus-workflows when prompted.

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

5. Step 5

   Start a new session and check

   Start a new Cline session so the tools and skills load. Ask: What’s my Locus balance?

Why does Cline need both the MCP server and the skills?

The MCP install gives Cline the Locus tools. It does not install skills. The skills teach Cline when and how to use those tools, so skipping them leaves an agent that has tools but no instructions.

npx skills add copies the three skill folders into the project for Cline. Run it again in each project where you want them.

How do I fix a Cline MCP OAuth error?

Remove the server, run the install command again, and pick Remote (HTTP) and OAuth.

• Remove the entry: cline mcp uninstall locus
• Leave the client ID blank so Cline registers itself with Locus.
• Check the URL is exactly https://api.paywithlocus.com/api/credits/mcp.
• Start a new session after any change.

What can Cline do with Locus connected?

Cline can search the Locus catalog, read an endpoint schema and price, and run the call against your credits. You do not need an account or key with each provider.

The core tools are search_apis, describe_api, estimate_cost, execute, get_call_result, get_balance, and get_locus_guide. locus-workflows lets Cline save and rerun multi-step jobs.
