What can go wrong

Even read-only tools carry cost. An agent in a retry loop can make thousands of API calls per minute, exhausting rate limits and running up bills.

How to control Oh My KEGG MCP

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

Cap read operations
{
  "batch_entry_lookup": {
    "limits": [
      {
        "counter": "batch_entry_lookup_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 Oh My KEGG MCP — 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.
