AI agents call tms_search_trans_memory to retrieve information from Phrase without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool searches and retrieves data from a translation memory without creating, modifying, or deleting any records. While it uses POST (which typically modifies data), the description and context indicate it is a read-only search query operation. No side effects or state changes occur. Severity is low because misuse would only expose existing localization data.
From the tool's definition Tool description explicitly states "Search for segments" and uses a POST endpoint to query a translation memory database. The function is retrieval-only with no modification, deletion, or execution of external operations.
Attacks that exploit this kind of access
Search for segments in a Phrase TMS translation memory. (POST /api2/v1/transMemories/{tmUid}/search). It is categorised as a Read tool in the Phrase MCP Server, which means it retrieves data without modifying state.
Register the Phrase MCP server in PolicyLayer and add a rule for tms_search_trans_memory: 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 Phrase. Nothing to install.
tms_search_trans_memory 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 tms_search_trans_memory 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 tms_search_trans_memory. 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.
tms_search_trans_memory is provided by the Phrase MCP server (phrase-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
