code_entity_history

Get the complete memory timeline for a code entity. BRIDGE TOOL: Shows all memories about a function/class ordered by time. Args: code_entity: Function/class/file name or qualified name.

How to control code_entity_history ↓

AI agents call code_entity_history to retrieve information from Qualixar/superlocalmemory without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Low Risk

This is a data retrieval tool that queries a persistent memory store to fetch historical information about code entities. It has no side effects—it only reads and returns timeline data sorted temporally.

From the tool's definition Tool retrieves and queries existing memory data ('Get the complete memory timeline', 'Shows all memories... ordered by time'). No modification, deletion, or execution of code indicated.

Documented attack patterns abuse exactly the kind of access code_entity_history gives an agent:

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "code_entity_history": {}
  }
}

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

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

What does the code_entity_history tool do? +

Get the complete memory timeline for a code entity. BRIDGE TOOL: Shows all memories about a function/class ordered by time. Args: code_entity: Function/class/file name or qualified name. It is categorised as a Read tool in the Qualixar/superlocalmemory MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on code_entity_history? +

Register the Qualixar/superlocalmemory MCP server in PolicyLayer and add a rule for code_entity_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 Qualixar/superlocalmemory. Nothing to install.

What risk level is code_entity_history? +

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

Can I rate-limit code_entity_history? +

Yes. Add a rate_limit block to the code_entity_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 code_entity_history completely? +

Set action: deny in the PolicyLayer policy for code_entity_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 code_entity_history? +

code_entity_history is provided by the Qualixar/superlocalmemory MCP server (qualixar/superlocalmemory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Qualixar/superlocalmemory tool call.
