Load a deduped_requests.txt file produced by the user's Burp
AI agents call dedup_load to retrieve information from Burp Mcp Plus without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and ingests a local file for analysis or processing. It performs a read operation without creating, modifying, deleting, or executing anything. The severity is low because file loading from a user-controlled path has minimal blast radius — it can only expose data the user already has access to. High confidence because the description is explicit about the read-only nature of the operation.
From the tool's definition Tool name and description: 'Load a `deduped_requests.txt` file produced by the user's Burp' — the verb 'load' indicates reading/retrieving a file that already exists, with no modification or deletion.
Documented attack patterns abuse exactly the kind of access dedup_load gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Burp Mcp Plus, and nothing reaches the server without passing your rules. This is the rule we recommend for dedup_load:
{
"version": "1",
"default": "deny",
"tools": {
"dedup_load": {}
}
}dedup_load is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Load a deduped_requests.txt file produced by the user's Burp. It is categorised as a Read tool in the Burp Mcp Plus MCP Server, which means it retrieves data without modifying state.
Register the Burp Mcp Plus MCP server in PolicyLayer and add a rule for dedup_load: 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 Burp Mcp Plus. Nothing to install.
dedup_load 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 dedup_load 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 dedup_load. 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.
dedup_load is provided by the Burp Mcp Plus MCP server (titaniumtushar/burp-mcp-plus). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Burp Mcp Plus, 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.
