THE RISK

Medium Risk

Why context_integrate_tool needs a policy

Tracking events from other MCP tools implies recording/writing data about tool invocations into the persistent context store. This is a Write operation as it creates or modifies stored records. Severity is medium because it could capture sensitive information from other tools' events across sessions, but it doesn't directly delete or execute arbitrary code.

POLICY

How to control context_integrate_tool

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "context_integrate_tool": {
      "limits": [
        {
          "counter": "context_integrate_tool_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

context_integrate_tool stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

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

FAQ

Questions about context_integrate_tool

What does the context_integrate_tool tool do? +

Track events from other MCP tools. It is categorised as a Write tool in the MCP Memory Keeper MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on context_integrate_tool? +

Register the MCP Memory Keeper MCP server in PolicyLayer and add a rule for context_integrate_tool: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MCP Memory Keeper. Nothing to install.

What risk level is context_integrate_tool? +

context_integrate_tool is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit context_integrate_tool? +

Yes. Add a rate_limit block to the context_integrate_tool rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block context_integrate_tool completely? +

Set action: deny in the PolicyLayer policy for context_integrate_tool. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides context_integrate_tool? +

context_integrate_tool is provided by the MCP Memory Keeper MCP server (mkreyman/mcp-memory-keeper). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every MCP Memory Keeper tool call.

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