AI agents call get_release_tags to retrieve information from Fred without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves or queries tags associated with FRED releases. No modification, deletion, code execution, or financial operation is possible. This is a read-only retrieval operation consistent with the server's stated purpose of querying Federal Reserve Economic Data.
From the tool's definition Tool name 'get_release_tags' follows the 'get_*' pattern consistent with sibling tools like get_release, get_release_dates, and get_category_tags. Server description states it 'retrieves' FRED data with 'no side effects'.
Attacks that exploit this kind of access
get_release_tags. It is categorised as a Read tool in the Fred MCP Server, which means it retrieves data without modifying state.
Register the Fred MCP server in PolicyLayer and add a rule for get_release_tags: 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 Fred. Nothing to install.
get_release_tags 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 get_release_tags 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 get_release_tags. 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.
get_release_tags is provided by the Fred MCP server (zachspar/fred-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
