Why compress_context needs a policy

With no description available, classification is uncertain. Based on the name alone, 'compress_context' likely reduces or summarizes in-memory/stored message context, which could be a Write (modifying stored context) or Read (just compressing for retrieval). Given the ambiguity, Other is assigned with low confidence. If it modifies stored context, Write would apply.

From the tool's definition Tool description is empty and uninformative; the tool name 'compress_context' suggests summarizing or reducing stored message context data.

POLICY

How to control compress_context

PolicyLayer is an MCP gateway — it sits between your AI agents and Amadeus-QQ-MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for compress_context:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "compress_context": {
      "limits": [
        {
          "counter": "compress_context_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

compress_context gets a rate cap, and everything else on the server is denied unless you say otherwise.

Create a free account and register Amadeus-QQ-MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

What MCP server provides compress_context? +

compress_context is provided by the Amadeus-QQ- MCP server (julesliu390/amadeus-qq-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Amadeus-QQ-MCP tool call.

Start from Amadeus-QQ-MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
