query · Pyke MCP Server MCP: Risk & Policy

WHAT IT DOES

What query does on Pyke MCP Server

AI agents invoke query to trigger actions in Pyke MCP 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 query needs a policy

Given the server context (Pyke logic programming engine with forward chaining inference and goal proving), a 'query' tool likely executes logical queries or goal-proving operations against a knowledge base, which constitutes execution of computational logic. The sibling tool 'prove_goal' suggests query execution semantics. However, the empty description reduces confidence.

From the tool's definition Tool name is 'query' on a logic programming/inference engine server; description is empty and uninformative.

Verdict

query Rate-limited

query 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Pyke MCP Server, so you can run agents against it safely.

FAQ

Questions about query

What does the query tool do? +

query. It is categorised as a Execute tool in the Pyke MCP 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 query? +

Register the Pyke MCP Server MCP server in PolicyLayer and add a rule for query: 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 Pyke MCP Server. Nothing to install.

What risk level is query? +

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

Can I rate-limit query? +

Yes. Add a rate_limit block to the query 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 query completely? +

Set action: deny in the PolicyLayer policy for query. 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 query? +

query is provided by the Pyke MCP Server MCP server (newjerseystyle/pyke-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
