tcga_differential_expression_analysis
AI agents call tcga_differential_expression_analysis to retrieve information from OrigeneMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool appears to retrieve and analyze genomic expression data from TCGA without modifying the underlying database. Expression analysis is a computational query operation (Read category). Severity is medium because misuse could expose sensitive patient genomic data or enable biased analysis pipelines, but the tool itself does not execute arbitrary code, delete data, or move money.
From the tool's definition Tool name 'tcga_differential_expression_analysis' indicates querying and analyzing expression data from The Cancer Genome Atlas (TCGA). The suffix '_analysis' suggests computational analysis of existing data rather than modification.
Documented attack patterns abuse exactly the kind of access tcga_differential_expression_analysis gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OrigeneMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for tcga_differential_expression_analysis:
{
"version": "1",
"default": "deny",
"tools": {
"tcga_differential_expression_analysis": {}
}
}tcga_differential_expression_analysis is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
tcga_differential_expression_analysis. It is categorised as a Read tool in the OrigeneMCP MCP Server, which means it retrieves data without modifying state.
Register the Origene MCP server in PolicyLayer and add a rule for tcga_differential_expression_analysis: 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 OrigeneMCP. Nothing to install.
tcga_differential_expression_analysis 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 tcga_differential_expression_analysis 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 tcga_differential_expression_analysis. 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.
tcga_differential_expression_analysis is provided by the Origene MCP server (gentel-lab/origenemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from OrigeneMCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
