AI agents call dedup_list 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 displays a list of existing dedup sources without creating, modifying, deleting, or executing any operations. It is a pure data retrieval function analogous to 'list' or 'get' operations, posing minimal risk even if invoked by an agent.
From the tool's definition Tool name 'dedup_list' and description 'List all registered dedup sources' indicate a query/retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access dedup_list 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_list:
{
"version": "1",
"default": "deny",
"tools": {
"dedup_list": {}
}
}dedup_list 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.
List all registered dedup sources. 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_list: 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_list 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_list 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_list. 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_list 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.
