Check the status of a deep research operation.
AI agents call gemini_check_research_tool to retrieve information from MCP Gemini without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves the current state of an existing research operation without creating, modifying, deleting, or executing anything. Status checks are read-only operations that return information about a process. The low severity reflects minimal blast radius—an AI agent cannot cause harm by checking research status.
From the tool's definition Tool name and description indicate a status-checking operation: 'Check the status of a deep research operation.' This is a query/retrieval action with no side effects.
Attacks that exploit this kind of access
Check the status of a deep research operation. It is categorised as a Read tool in the MCP Gemini MCP Server, which means it retrieves data without modifying state.
Register the MCP Gemini MCP server in PolicyLayer and add a rule for gemini_check_research_tool: 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 MCP Gemini. Nothing to install.
gemini_check_research_tool 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 gemini_check_research_tool 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 gemini_check_research_tool. 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.
gemini_check_research_tool is provided by the MCP Gemini MCP server (mcp-gemini-crunchtools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
