research
AI agents call research to retrieve information from Free Search without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Given the empty description and the context of sibling tools that perform data retrieval and querying, 'research' most likely performs information gathering or search operations. The server explicitly focuses on reading and fetching content without side effects. Confidence is moderate (0.7) due to the missing description, but the surrounding context strongly suggests a Read classification.
From the tool's definition Tool named 'research' is a sibling of 'fetch', 'fetch_batch', 'extract_structured', and 'compare'—all read-only operations. The server description emphasizes 'search the web, fetch pages, and read documents' with no mention of modification or execution.
Attacks that exploit this kind of access
research. It is categorised as a Read tool in the Free Search MCP Server, which means it retrieves data without modifying state.
Register the Free Search MCP server in PolicyLayer and add a rule for research: 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 Free Search. Nothing to install.
research 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 research 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 research. 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.
research is provided by the Free Search MCP server (sweetcornna/free-search-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
