How to connect

How to connect mcp-sentinel to Claude

The server address to paste into Claude settings:

https://mcp-sentinel--pasihakamaki.run.tools

  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 mcp-sentinel to ChatGPT

The server address to paste into ChatGPT settings:

https://mcp-sentinel--pasihakamaki.run.tools

  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.

Authorization

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

How to connect mcp-sentinel to Cursor

The server address to paste into Cursor settings:

https://mcp-sentinel--pasihakamaki.run.tools

Fastest: click Open in Cursor below and confirm the prompt.

Manually:

  1. In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
  2. Paste the JSON copied below into ~/.cursor/mcp.json (per project: .cursor/mcp.json in the repo root).
  3. Save the file. The server appears in the MCP list; authorize it there if asked.

Authorization

If the service needs sign-in, an authorize button appears next to the server in the MCP list.

Server tool list (3)

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

audit_mcp_serverPerforms an automated synthetic health, protocol compliance, schema validation, and credential security audit on any remote Model Context Protocol (MCP) server. Use this tool when you need to comprehensively verify whether an external MCP server is reachable, measure round-trip latency, validate tool schemas against JSON Schema draft-07/2020-12 specifications, detect broken parameter definitions, and check for exposed API tokens or credentials. Returns a detailed markdown diagnostic report and structured status flags.
verify_mcp_protocolValidates JSON-RPC 2.0 protocol compatibility and version negotiation with a remote MCP server without executing a full synthetic vulnerability scan. Use this tool when you specifically need to test whether a remote server supports modern Stateless Core ("2026-07-28"), structured outputs ("2025-06-18"), icons metadata ("2025-11-25"), or legacy handshakes ("2024-11-05"), benchmark handshake latency, or inspect declared server capabilities and tool counts.
get_monitor_badgeGenerates dynamic SVG status badge links and Markdown embed snippets for an MCP Sentinel uptime monitor. Use this tool when you want to display the real-time operational status, protocol version, and uptime badge of a monitored MCP server directly inside a GitHub repository README, developer documentation, or status page.
