get_cell
AI agents call get_cell to retrieve information from ModelRisk MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears designed to retrieve cell values from Excel models. It has no side effects—it queries data without creating, modifying, deleting, or executing arbitrary operations. The empty description slightly reduces confidence, but the naming convention and tool ecosystem make Read classification appropriate. Severity is low because cell retrieval poses minimal risk even if misused by an AI agent.
From the tool's definition Tool name 'get_cell' indicates retrieval of cell data from an Excel workbook. Given the ModelRisk context (Monte Carlo risk modeling in Excel), this tool queries existing workbook data without modification.
Attacks that exploit this kind of access
get_cell. It is categorised as a Read tool in the ModelRisk MCP MCP Server, which means it retrieves data without modifying state.
Register the ModelRisk MCP server in PolicyLayer and add a rule for get_cell: 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 ModelRisk MCP. Nothing to install.
get_cell 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 get_cell 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 get_cell. 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.
get_cell is provided by the ModelRisk MCP server (vosesoftware/modelrisk-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
