sampleLLM · MCP Elicitations Demo Server MCP: Risk & Policy

WHAT IT DOES

What sampleLLM does on MCP Elicitations Demo Server

AI agents invoke sampleLLM to trigger actions in MCP Elicitations Demo Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why sampleLLM needs a policy

This tool triggers an external LLM sampling operation via MCP, which constitutes executing an external operation. The effects depend on the arguments passed (prompt, model parameters, etc.). It is not a simple read since it actively invokes a model inference call, which may have cost implications and non-deterministic outputs.

Verdict

sampleLLM Rate-limited

sampleLLM stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about sampleLLM

What does the sampleLLM tool do? +

Samples from an LLM using MCP. It is categorised as a Execute tool in the MCP Elicitations Demo Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on sampleLLM? +

Register the MCP Elicitations Demo Server MCP server in PolicyLayer and add a rule for sampleLLM: 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 Elicitations Demo Server. Nothing to install.

What risk level is sampleLLM? +

sampleLLM is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit sampleLLM? +

Yes. Add a rate_limit block to the sampleLLM 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.

How do I block sampleLLM completely? +

Set action: deny in the PolicyLayer policy for sampleLLM. 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.

What MCP server provides sampleLLM? +

sampleLLM is provided by the MCP Elicitations Demo Server MCP server (soriat/soria-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
