Plot a heatmap of smoothed gene expression by chromosome.
AI agents call chromosome_heatmap to retrieve information from Infercnv-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The chromosome_heatmap tool performs data visualization only. It reads processed gene expression data and generates a graphical representation (heatmap). This is a read operation with no capability to modify data, execute arbitrary code, delete information, or cause financial impact. The operation is purely analytical with no reversible or irreversible side effects on the underlying data.
From the tool's definition Tool is described as 'Plot a heatmap of smoothed gene expression by chromosome' - a visualization/output operation that retrieves and displays data without modification, creation, deletion, or external side effects.
Attacks that exploit this kind of access
Plot a heatmap of smoothed gene expression by chromosome. It is categorised as a Read tool in the Infercnv-MCP MCP Server, which means it retrieves data without modifying state.
Register the Infercnv- MCP server in PolicyLayer and add a rule for chromosome_heatmap: 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.
chromosome_heatmap is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the chromosome_heatmap 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.
Set action: deny in the PolicyLayer policy for chromosome_heatmap. 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.
chromosome_heatmap 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.
