    How to connect FHI MCP Server Security Audit to Claude

    The server address to paste into Claude settings:

    https://polished-truth-c514.fhi-llc-1118.workers.dev/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 FHI MCP Server Security Audit to ChatGPT

    The server address to paste into ChatGPT settings:

    https://polished-truth-c514.fhi-llc-1118.workers.dev/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.

    payment_infoFree guide to the FHI MCP tools, Base-USDC x402 payment flow, and per-tool prices.
    domain_change_evidenceStateful DNS, CAA, and certificate-transparency monitoring for a public domain. The first call establishes a baseline; later calls return evidence changes and certificate-expiry signals. ($0.01 USDC on Base)
    package_install_preflightnpm or PyPI install preflight: blocks missing packages, detects near-name typosquats when an expected name is supplied, and checks OSV advisories. ($0.003 USDC on Base)
    sec_material_event_deltaNew SEC 8-K, 6-K, and late-filing evidence since a cursor date; accepts a ticker or CIK. ($0.01 USDC on Base)
    mcp_payment_preflightMCP server security audit before an agent connects or pays: probes initialize and tools/list, then returns an ALLOW, CAUTION, or BLOCK risk score for command, filesystem, or wallet capabilities; prompt-injection or data-exfiltration signals; permissive JSON-schema inputs; missing HSTS; and a large tool surface. Does not execute tools. ($0.01 USDC on Base)
    mcp_change_evidenceStateful live remote-MCP monitor for tool-rug-pull and tool-poisoning risk. Establishes an endpoint baseline, then detects added or removed tools, altered tool descriptions, risk-score changes, and newly observed high-risk capability signals before an agent reconnects or pays. Unlike a manifest diff, it fetches the live endpoint and retains the prior observation. ($0.003 USDC on Base)
    mcp_vendor_due_diligenceOne decision-ready due-diligence dossier before an agent adopts or pays an MCP vendor: live MCP metadata and tool-risk preflight, DNS/CAA/certificate evidence, plus optional SEC material-filing evidence for a public company. Does not execute vendor tools or certify safety. ($0.10 USDC on Base)
