AI agents call find_similar_pages to retrieve information from Personal Knowledge MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only search/query operation that retrieves and compares existing data to provide deduplication recommendations. It has no side effects—it does not create, modify, delete, or execute code. The low severity reflects minimal risk if misused, as it only returns informational suggestions for human review.
From the tool's definition Tool description indicates it 'finds similar pages' and 'returns merge/review/distinct suggestions' for deduplication decisions.
Documented attack patterns abuse exactly the kind of access find_similar_pages gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Personal Knowledge MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for find_similar_pages:
{
"version": "1",
"default": "deny",
"tools": {
"find_similar_pages": {}
}
}find_similar_pages is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Personal Knowledge MCP Server MCP server in PolicyLayer and add a rule for find_similar_pages: 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 Personal Knowledge MCP Server. Nothing to install.
find_similar_pages 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 find_similar_pages 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 find_similar_pages. 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.
find_similar_pages is provided by the Personal Knowledge MCP Server MCP server (kyodule/personal-knowledge-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Personal Knowledge MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
