    How to connect

    How to connect Major Labs to Claude

    The server address to paste into Claude settings:

    https://majorlabs.co/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 Major Labs to ChatGPT

    The server address to paste into ChatGPT settings:

    https://majorlabs.co/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.

    Server tool list (5)

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

    get_trust_indexThe weekly Agent Trust Index: one composite score (0-100) for how safe the agentic web is to transact on, fused from code-safety, identity, and supply-chain pillars, with the per-pillar numbers and methodology version.
    get_mcp_ecosystem_statsAggregate statistics from the Major Labs weekly sweep of the MCP server ecosystem: census size, activity, transport and language breakdowns, and security/identity aggregates. Firsthand, read-only measurement.
    list_incidentsA dated, sourced record of frontier AI control incidents: containment escapes, unsanctioned live-system actions, evaluation incidents, and insider disclosures, with published inclusion criteria and sources for every claim.
    get_agent_identity_trackerEvery announced framework, protocol, standard, and regulation for AI agent identity, delegation, and know-your-agent (KYA) verification, dated and traced to primary sources.
    get_threshold_watchDated, hashed snapshots of the frontier labs' published safety frameworks, with diffs when a framework changes. A change event means a lab edited its safety commitments.
