Gemini CLI

Gemini CLI connects to postevi over Streamable HTTP with OAuth. It works on the free tier that comes with a personal Google account, too.

All integrations

With a command

Adds the server for your user; you sign in from inside Gemini CLI.

Run this in your terminal. The -s user flag makes the server available in every project.
```
gemini mcp add --transport http -s user postevi https://postevi.app/api/mcp
```
Start Gemini CLI and type the auth command.
```
/mcp auth postevi
```
Sign in to postevi in the browser window that opens and pick a workspace.

With settings.json

When you write the entry by hand, Streamable HTTP goes in the httpUrl field.

Open ~/.gemini/settings.json.

Add this entry under mcpServers.

{
  "mcpServers": {
    "postevi": {
      "httpUrl": "https://postevi.app/api/mcp"
    }
  }
}

Restart Gemini CLI and sign in to postevi with the auth command.
```
/mcp auth postevi
```

With an API key

OAuth sign-in doesn't work over SSH, in containers or anywhere without a browser; send the key in a header there.

Create an API key on the AI page of the dashboard and pick its permissions.
Put the key in the environment variable below.
```
export POSTEVI_API_KEY=postevi_sk_...
```

Add the Authorization header to the settings.json entry.

{
  "mcpServers": {
    "postevi": {
      "httpUrl": "https://postevi.app/api/mcp",
      "headers": { "Authorization": "Bearer $POSTEVI_API_KEY" }
    }
  }
}

The url field is for SSE; for postevi, use httpUrl.
Without -s user, gemini mcp add only adds the server to the project you're in.
