AI agents call finance.figi-search to retrieve information from Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries a securities database (OpenFIGI) to retrieve information about financial instruments. It is purely informational—searching and returning security identifiers and metadata with optional filtering. There are no side effects: no data is created, modified, deleted, or transacted. It is analogous to a financial data lookup service, making it a Read operation.
From the tool's definition Tool performs 'Free-text security search' and 'Returns relevance-ranked FIGIs + metadata'; no modification, deletion, or financial transaction capability described.

Free-text security search across global exchanges via OpenFIGI. Give a query (name/ticker/description), optionally narrow by exchCode/securityType/marketSector (Equity, Corp, Govt, Mtge, Muni, Pfd, Comdty, Index, Curncy). Returns relevance-ranked FIGIs + metadata and a next cursor (pass back as start). Free, open symbology. Distinct from finance.figi (exact id → FIGI) — this is discovery by name. It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.
Register the MCP server in PolicyLayer and add a rule for finance.figi-search: 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 Mcp. Nothing to install.
finance.figi-search 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 finance.figi-search 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 finance.figi-search. 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.
finance.figi-search is provided by the MCP server (@2sio/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
