Perform deep research on a topic with content extraction and analysis

How to control deep_research ↓

AI agents call deep_research to retrieve information from MCP Web Research Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Low Risk

This tool retrieves and analyzes web content for research purposes. Content extraction and analysis are passive read operations that return information to the user without side effects, persistent changes, or external execution. The low severity reflects minimal risk of unintended harm even with misuse—worst case would be retrieving irrelevant or sensitive information, but no destructive or financial consequences.

From the tool's definition Tool performs 'deep research on a topic with content extraction and analysis' - describes information retrieval and analysis operations.

Documented attack patterns abuse exactly the kind of access deep_research gives an agent:

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Web Research Server, and nothing reaches the server without passing your rules. This is the rule we recommend for deep_research:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "deep_research": {}
  }
}

deep_research is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register MCP Web Research Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
