AI agents call remember_similar_texts to retrieve information from Mcp Rag Local without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries a local vector database to find and return semantically similar texts. It has no side effects—it only retrieves data without creating, modifying, deleting, or executing operations. The empty description lowers confidence slightly, but the naming pattern and server architecture strongly indicate a retrieval function.
From the tool's definition Tool name 'remember_similar_texts' combined with server purpose of 'retrieving text passages based on semantic meaning' and sibling tool 'memorize_text' indicates this retrieves stored information.
Documented attack patterns abuse exactly the kind of access remember_similar_texts gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Rag Local, and nothing reaches the server without passing your rules. This is the rule we recommend for remember_similar_texts:
{
"version": "1",
"default": "deny",
"tools": {
"remember_similar_texts": {}
}
}remember_similar_texts is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

remember_similar_texts. It is categorised as a Read tool in the Mcp Rag Local MCP Server, which means it retrieves data without modifying state.
Register the Mcp Rag Local MCP server in PolicyLayer and add a rule for remember_similar_texts: 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 Rag Local. Nothing to install.
remember_similar_texts is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the remember_similar_texts 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.
Set action: deny in the PolicyLayer policy for remember_similar_texts. 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.
remember_similar_texts is provided by the Mcp Rag Local MCP server (renl/mcp-rag-local). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mcp Rag Local, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
