MOST DANGEROUS TOOLS

High Risk
Write · High complete_reddit_oauth OAuth completion tools typically write/store authentication tokens and credentials, enabling subsequent access to personal Reddit data. Write · High complete_spotify_oauth Completing an OAuth flow typically involves storing or writing access/refresh tokens to persistent storage. Write · Medium complete_youtube_oauth This tool completes an OAuth2 flow and stores/writes authentication tokens for YouTube. Write · High setup_spotify_oauth This tool performs OAuth setup for Spotify, which creates/modifies authentication tokens and establishes access to personal data.

13 of PersonalizationMCP's 88 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

HOW TO CONTROL PERSONALIZATIONMCP

PolicyLayer is an MCP gateway — it sits between your AI agents and PersonalizationMCP, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations
{
  "auto_refresh_spotify_token_if_needed": {
    "limits": [
      {
        "counter": "auto_refresh_spotify_token_if_needed_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations
{
  "auto_refresh_reddit_token_if_needed": {
    "limits": [
      {
        "counter": "auto_refresh_reddit_token_if_needed_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

  1. Create a free account and register PersonalizationMCP — nothing to install.
  2. Add these rules — paste them, or build them visually. Tune the limits to your setup.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

How do I prevent bulk modifications through PersonalizationMCP? +

The PersonalizationMCP server has 13 write tools including auto_refresh_spotify_token_if_needed, follow_artists_or_users, follow_playlist. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach PersonalizationMCP.

How many tools does the Personalization MCP server expose? +

88 tools across 2 categories: Read, Write. 75 are read-only. 13 can modify, create, or delete data.

How do I enforce a policy on PersonalizationMCP? +

Register the Personalization MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every PersonalizationMCP tool call.

Deterministic rules across all 88 PersonalizationMCP tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
