POLICY

How to control GribStream MCP

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

Cap read operations

{
  "gribstream_get_dataset": {
    "limits": [
      {
        "counter": "gribstream_get_dataset_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

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

FAQ

Questions about GribStream MCP

Is the GribStream MCP server safe to use without restrictions? +

The GribStream MCP server is primarily read-only with 10 read tools. While it cannot modify data, an agent in a retry loop can make thousands of API calls per minute, exhausting rate limits and running up costs. Rate limiting is still recommended.

How many tools does the GribStream MCP server expose? +

12 tools across 3 categories: Execute, Read, Write. 10 are read-only. 2 can modify, create, or delete data.

How do I enforce a policy on GribStream MCP? +

Register the GribStream 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 GribStream MCP tool call.

Deterministic rules across all 12 GribStream MCP tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
