THE RISK

Low Risk

Why get_memory_history needs a policy

This is a read operation that retrieves audit/change history for a memory record. It has no side effects—it only fetches existing data. The blast radius if misused by an AI agent is minimal, as it cannot create, modify, delete, or execute anything. The exposure is limited to information disclosure of memory change history, which is low-impact compared to other categories.

From the tool's definition Tool name 'get_memory_history' and description 'Get change history for a specific memory' indicate a retrieval operation that queries historical data without modifying, deleting, or executing external operations.

POLICY

How to control get_memory_history

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_memory_history": {}
  }
}

get_memory_history is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register AGI MCP Server — 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 get_memory_history

What does the get_memory_history tool do? +

Get change history for a specific memory. It is categorised as a Read tool in the AGI MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on get_memory_history? +

Register the AGI MCP Server MCP server in PolicyLayer and add a rule for get_memory_history: 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 AGI MCP Server. Nothing to install.

What risk level is get_memory_history? +

get_memory_history is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit get_memory_history? +

Yes. Add a rate_limit block to the get_memory_history 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 get_memory_history completely? +

Set action: deny in the PolicyLayer policy for get_memory_history. 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 get_memory_history? +

get_memory_history is provided by the AGI MCP Server MCP server (quixiai/agi-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every AGI MCP Server tool call.

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