You need your MCP URL first. Get your MCP URL

Any assistant that can add a remote MCP server over HTTP (Streamable HTTP) can use your MCP URL. Add it as a custom server or connector, with no extra authentication.

https://mcp.posty5.com/t/YOUR-TOKEN/mcp

Windsurf

Add this to Windsurf’s MCP configuration.

{
  "mcpServers": {
    "posty5": {
      "serverUrl": "https://mcp.posty5.com/t/YOUR-TOKEN/mcp"
    }
  }
}

Gemini CLI

Add this to the Gemini CLI settings file. ~/.gemini/settings.json

{
  "mcpServers": {
    "posty5": {
      "httpUrl": "https://mcp.posty5.com/t/YOUR-TOKEN/mcp"
    }
  }
}

n8n

Add an MCP Client Tool to your AI Agent node.
Paste your MCP URL as the endpoint, choose HTTP Streamable as the transport, and leave authentication off.

To call Posty5 from a fixed workflow step rather than through an agent, use the Posty5 n8n nodes instead. n8n-nodes

MCP Inspector

The MCP Inspector is the protocol’s own test client. Use it to see exactly which tools your URL offers.

Run the command below in a terminal.
Terminal window
```
npx @modelcontextprotocol/inspector
```
In the Inspector, choose the Streamable HTTP transport.
Paste your MCP URL into the URL field, choose Connect, then List Tools.

The local package

For an assistant that starts MCP servers on your computer, run Posty5’s package instead of using a URL. It needs Node.js 20 or later and an API key. API keys and authentication

{
  "mcpServers": {
    "posty5": {
      "command": "npx",
      "args": ["-y", "@posty5/mcp"],
      "env": {
        "POSTY5_API_KEY": "YOUR_API_KEY",
        "POSTY5_MCP_TOOLSETS": "short-links,qr-codes",
        "POSTY5_MCP_ACCESS": "write"
      }
    }
  }
}

Variable	Required	Meaning
`POSTY5_API_KEY`	Yes	The API key every call uses. It is never printed.
`POSTY5_MCP_TOOLSETS`	No	The tool groups, separated by commas. By default, account, short-links, qr-codes, html-hosting and social-publisher.
`POSTY5_MCP_ACCESS`	No	read, write (the default) or full.
`POSTY5_AI_MODEL`	No	The model to record when a call does not name one.

The local package keeps no activity log, and what it creates is marked as declared by the client rather than confirmed by Posty5’s MCP server.

Check that it works

Start a new chat and ask

Which Posty5 account am I connected to?

The assistant should use the Posty5 Who am I tool and answer with your account and plan. If it does not, see Troubleshooting
