Personio HR + Gemini

Access employee records, attendances, absences, and time-offs via the Personio REST API. Personio is the dominant HR platform for DACH SMBs.

Prerequisites

See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:

PERSONIO_TOKEN

Step 1 — Get credentials

Authentication model — IMPORTANT: Personio's /auth endpoint is not a standard OAuth2 flow. You POST {client_id, client_secret} once and get back a short-lived bearer token, which is then passed as Authorization: Bearer <token> on every request. Each successful API response ALSO returns a new token in its Authorization response header that must be used for the next call — effectively a token-rotation scheme. This adapter uses a single long-lived bearer token supplied by you (PERSONIO_TOKEN).

…(continued in the in-app connector instructions)

Step 2 — Install the adapter

curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d

Step 3 — Add the connector in Gemini

Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide shows YOUR_SERVER_ID.

Gemini CLI reads MCP servers from ~/.gemini/settings.json (or %APPDATA%\gemini\settings.json on Windows). Add:

{
  "mcpServers": {
    "anythingmcp": {
      "httpUrl": "https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID",
      "headers": { "X-API-Key": "YOUR_MCP_API_KEY" }
    }
  }
}
  1. Get your MCP API key from AnythingMCP → MCP Servers → your server → API keys.
  2. Save the file and restart gemini.
  3. Run /mcp inside the Gemini CLI — Personio HR should be listed as available.
  4. Vertex AI Studio: pass https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID to the tools array of your request with the same X-API-Key header.

Does Gemini 1.5 Pro or 2.x support MCP? Yes — Gemini CLI ≥ 0.4 and Vertex AI tools API both accept MCP httpUrl connectors with custom headers.
