infercnv · Infercnv- MCP: Risk & Policy

WHAT IT DOES

What infercnv does on Infercnv-MCP

AI agents invoke infercnv to trigger actions in Infercnv-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 infercnv needs a policy

This tool executes a CNV inference algorithm (computation) over scRNA-seq data using the infercnvpy framework. It triggers an external computational process that processes and transforms data, fitting the Execute category. It is not purely reading existing data (it computes/derives new results), not writing user-created data reversibly in a simple sense, and not destructive or financial.

From the tool's definition "Infer Copy Number Variation (CNV) by averaging gene expression over genomic regions" — performs a computational inference/analysis operation over data

Verdict

infercnv Rate-limited

infercnv 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 Infercnv-MCP, so you can run agents against it safely.

FAQ

Questions about infercnv

What does the infercnv tool do? +

Infer Copy Number Variation (CNV) by averaging gene expression over genomic regions. It is categorised as a Execute tool in the Infercnv-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 infercnv? +

Register the Infercnv- MCP server in PolicyLayer and add a rule for infercnv: 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 Infercnv-MCP. Nothing to install.

What risk level is infercnv? +

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

Can I rate-limit infercnv? +

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

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

infercnv is provided by the Infercnv- MCP server (scmcphub/infercnv-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
