AI agents call get_relative_value to retrieve information from Wrds without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to retrieve relative value metrics for financial analysis purposes, consistent with the server's role in enabling queries of bond and credit data. No description is provided, which lowers confidence slightly, but the naming convention and sibling tools strongly indicate this is a data retrieval operation with no side effects.
From the tool's definition Tool name 'get_relative_value' suggests data retrieval. Sibling tools (get_bond_price_history, get_bond_yield_history, get_coverage_ratios, get_credit_ratings) are all Read operations that query financial metrics without modification.
Attacks that exploit this kind of access
get_relative_value. It is categorised as a Read tool in the Wrds MCP Server, which means it retrieves data without modifying state.
Register the Wrds MCP server in PolicyLayer and add a rule for get_relative_value: 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 Wrds. Nothing to install.
get_relative_value 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_relative_value 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_relative_value. 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_relative_value is provided by the Wrds MCP server (marianosalinas/wrds_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
