WHAT IT DOES

What calculate_stats does on ContextForge MCP Gateway

AI agents invoke calculate_stats to trigger actions in ContextForge MCP Gateway. 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 calculate_stats needs a policy

The tool description indicates it performs calculations with multiple operations, which goes beyond a simple read/query. 'Perform calculation' implies executing logic, possibly with side effects depending on arguments. However, the description is vague and lacks specifics, lowering confidence. It is categorized as Execute rather than Read because it actively computes rather than merely retrieving stored data.

From the tool's definition 'Perform calculation with multiple operations' — the phrase 'multiple operations' suggests it may execute compound logic beyond simple retrieval, and the parenthetical 'testing complex output' implies execution of varied computational steps

Verdict

calculate_stats Rate-limited

calculate_stats 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 calculate_stats

What does the calculate_stats tool do? +

Perform calculation with multiple operations (testing complex output). It is categorised as a Execute tool in the ContextForge MCP Gateway MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on calculate_stats? +

Register the ContextForge MCP Gateway MCP server in PolicyLayer and add a rule for calculate_stats: 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 ContextForge MCP Gateway. Nothing to install.

What risk level is calculate_stats? +

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

Can I rate-limit calculate_stats? +

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

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

calculate_stats is provided by the ContextForge MCP Gateway MCP server (jrmatherly/mcp-context-forge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
