Scan for duplicate content across Claude Code conversations. Finds duplicate conversations, images, and documents that waste storage and context space.
AI agents call find_duplicates to retrieve information from Claude Code Toolkit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
find_duplicates performs content analysis and discovery without altering, deleting, or executing anything. It identifies waste patterns to inform cleanup decisions but does not act on them (other tools like cleanup_backups and clean_traces handle actual removal). This is purely informational/observability, fitting the Read category with low severity due to negligible misuse blast radius.
From the tool's definition Tool description explicitly states it 'scans' for duplicates—a read-only operation that retrieves and analyzes existing data. No modifications, deletions, or external execution occur.
Documented attack patterns abuse exactly the kind of access find_duplicates gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Claude Code Toolkit, and nothing reaches the server without passing your rules. This is the rule we recommend for find_duplicates:
{
"version": "1",
"default": "deny",
"tools": {
"find_duplicates": {}
}
}find_duplicates is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Scan for duplicate content across Claude Code conversations. Finds duplicate conversations, images, and documents that waste storage and context space. It is categorised as a Read tool in the Claude Code Toolkit MCP Server, which means it retrieves data without modifying state.
Register the Claude Code Toolkit MCP server in PolicyLayer and add a rule for find_duplicates: 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 Claude Code Toolkit. Nothing to install.
find_duplicates 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_duplicates 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_duplicates. 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_duplicates is provided by the Claude Code Toolkit MCP server (asifkibria/claude-code-toolkit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Claude Code Toolkit, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
