AI agents call terminology.translate to retrieve information from FhirMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
terminology.translate performs a read-only code translation operation using ConceptMap resources. It retrieves equivalent codes across different coding systems but does not create, modify, delete, or execute external operations. While it accesses healthcare terminology data, the operation is strictly informational lookup with no side effects.
From the tool's definition Tool description states 'Translate a code from one system to another using ConceptMap' — this is a lookup/translation operation that queries terminology data without modifying it.
Attacks that exploit this kind of access
Translate a code from one system to another using ConceptMap. It is categorised as a Read tool in the FhirMCP MCP Server, which means it retrieves data without modifying state.
Register the Fhir MCP server in PolicyLayer and add a rule for terminology.translate: 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 FhirMCP. Nothing to install.
terminology.translate 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 terminology.translate 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 terminology.translate. 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.
terminology.translate is provided by the Fhir MCP server (xsovx/fhir-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
