Cross-map between ICD-10 and MedDRA terminology. Provides conceptual mapping guidance for translating diagnoses between coding systems — critical for regulatory submissions, REMS, and pharmacovigilance.
AI agents call crossmap_icd_meddra to retrieve information from Medterms without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and presents conceptual mappings between standardized medical coding systems. It is fundamentally a reference/lookup operation (Read category) with no side effects—it does not create, modify, delete, or execute operations. While the output is used in regulatory contexts (REMS, pharmacovigilance), the tool itself only provides read-only translation guidance.
From the tool's definition Tool performs cross-mapping lookup between medical terminologies (ICD-10 and MedDRA). Description emphasizes 'mapping guidance' and 'translating' between coding systems—retrieval and reference operations. No modification, deletion, or code execution mentioned.
Attacks that exploit this kind of access
Cross-map between ICD-10 and MedDRA terminology. Provides conceptual mapping guidance for translating diagnoses between coding systems — critical for regulatory submissions, REMS, and pharmacovigilance. It is categorised as a Read tool in the Medterms MCP Server, which means it retrieves data without modifying state.
Register the Medterms MCP server in PolicyLayer and add a rule for crossmap_icd_meddra: 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 Medterms. Nothing to install.
crossmap_icd_meddra 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 crossmap_icd_meddra 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 crossmap_icd_meddra. 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.
crossmap_icd_meddra is provided by the Medterms MCP server (pubspro/medterms-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
