AI agents call translate_identifiers to retrieve information from Altmetric without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though translate_identifiers only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access translate_identifiers gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Translate research output identifiers (DOIs, PMIDs, arXiv IDs, etc.) into Altmetric IDs. Useful for discovering which identifiers Altmetric has data for. Supports batch translation of up to 100,000 identifiers per request. The identifier type is auto-detected. This is a commercial feature requiring a paid API key.. It is categorised as a Read tool in the Altmetric MCP Server, which means it retrieves data without modifying state.
Register the Altmetric MCP server in PolicyLayer and add a rule for translate_identifiers: 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 Altmetric. Nothing to install.
translate_identifiers 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 translate_identifiers 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 translate_identifiers. 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.
translate_identifiers is provided by the Altmetric MCP server (altmetric/altmetric-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
