Selzy MCP endpoint and transport

https://mcp.selzy.com/mcp

Transport: unknown
Docs: Official Selzy MCP docs

Connect Selzy without code

Selzy's docs confirm it works in Claude. You don't need a terminal or a config file. Check Selzy's docs first: some vendors give you a personal URL or an API key to use in place of the plain endpoint.

Claude (web and desktop app)

If Selzy shows up when you browse connectors in Claude, connect it from there instead. That skips steps 2 to 4.

In Claude, open Customize → Connectors.
Click + Add, then Add custom connector.
Name it “Selzy”, paste the server URL https://mcp.selzy.com/mcp, and click Continue.
Review the sign-in settings Claude detected and click Add.
Click Connect and sign in to Selzy. Then ask Claude something like “What can the Selzy connector do?”

On Team and Enterprise plans, an Owner adds the connector first under Organization settings → Connectors → Add → Custom → Web. Each person then connects it from Customize → Connectors. Free plans can add one custom connector.

Steps from the Claude Help Center: support.claude.com, checked 2026-10-16

From Selzy's docs: In Claude, add a custom connector for https://mcp.selzy.com/mcp and authorize your Selzy account. In Claude Code, type /mcp. Selzy has tested the integration with Claude and Claude Code. A send requires explicit confirmation in the chat, and the campaign then waits for Selzy moderation. One connection works with one Selzy project at a time.Source: selzy.com, checked 2026-10-30

Developer setup (Claude Code, Cursor)

Add this to .mcp.json (Claude Code, project root) or ~/.cursor/mcp.json (Cursor). Remove the // comment line if your client requires strict JSON.

{
  "mcpServers": {
    "selzy": {
      "url": "https://mcp.selzy.com/mcp"
    }
  }
}

Add the endpoint to your client config (above), or as a custom connector in Claude.
Complete the OAuth sign-in. In Claude Code, run /mcp and pick the server.
Test it with a prompt like: “List the tools the Selzy MCP server exposes.”

Selzy MCP authentication

Sign in with OAuth in your client (run /mcp in Claude Code). Do it once interactively, and the client stores and refreshes the token.
