list_distributions
AI agents call list_distributions 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 retrieves or enumerates distributions without modifying state, executing code, or causing side effects. Even if it reads from a workbook, it performs no destructive or executable operations. Low severity due to limited blast radius if misused—listing distributions carries minimal risk.
From the tool's definition Tool name 'list_distributions' combined with server context of Monte Carlo risk modeling suggests querying available probability distributions.
Attacks that exploit this kind of access
list_distributions. 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 list_distributions: 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.
list_distributions 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 list_distributions 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 list_distributions. 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.
list_distributions 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.
