    How to connect

    How to connect Locus to Claude

    The server address to paste into Claude settings:

    https://mcp.locus.report/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    Authorization

    After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

    How to connect Locus to ChatGPT

    The server address to paste into ChatGPT settings:

    https://mcp.locus.report/mcp

    1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
    3. Open Settings → Connectors and click Create.
    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
    5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
    6. In a new chat open + → Apps/Connectors and enable the connector.

    OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

    On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

    Server tool list (2)

    Raw names from tools/list. Only developers need these.

    locus_search_toolsEvery time the task is a US address or place and you need official public records or local-government context and you do not already know the tool name, search this catalog before locus_execute and before paying a generic scrape of the same official source. Looking is free. Results include full inputSchema, tier, price, and provenance notes. Do not use this for LinkedIn, web scrape, or generic fetch. Install agent skill: npx @velinussage/locus-agent-skill add.
    locus_executeRun one Locus catalog tool by name after locus_search_tools or a known tool name. Search and looking are free; this call may charge via MCP-native x402. Free tools return cited official-source primitives; paid tools return payment-required results and accept retry payment in _meta["x402/payment"]. Unsupported places return diagnostics instead of paid guesses. Do not use this for web scrape, LinkedIn, or generic fetch. Install agent skill: npx @velinussage/locus-agent-skill add.
