analyze_single_variant · SPIRED-Stab MCP: Risk & Policy

WHAT IT DOES

What analyze_single_variant does on SPIRED-Stab MCP

AI agents invoke analyze_single_variant to trigger actions in SPIRED-Stab MCP. 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 analyze_single_variant needs a policy

Based on the server context, this tool likely executes a single variant stability analysis using the SPIRED-Stab model via Docker-based inference. Sibling tools like 'submit_stability_prediction' and 'submit_batch_mutation_analysis' suggest an execution/compute pattern. With an empty description, confidence is low, but Execute is the most plausible category given the computational inference context.

From the tool's definition Tool name is 'analyze_single_variant' on a server that runs Docker-based deep learning inference for protein stability prediction. Description is empty.

Verdict

analyze_single_variant Rate-limited

analyze_single_variant 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 SPIRED-Stab MCP, so you can run agents against it safely.

FAQ

Questions about analyze_single_variant

What does the analyze_single_variant tool do? +

analyze_single_variant. It is categorised as a Execute tool in the SPIRED-Stab MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on analyze_single_variant? +

Register the SPIRED-Stab MCP server in PolicyLayer and add a rule for analyze_single_variant: 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 SPIRED-Stab MCP. Nothing to install.

What risk level is analyze_single_variant? +

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

Can I rate-limit analyze_single_variant? +

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

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

analyze_single_variant is provided by the SPIRED-Stab MCP server (macromnex/spired_stab_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
