AI agents call finance.figi 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 is a pure lookup/reference tool that retrieves financial instrument metadata without modifying data or executing trades. While it operates in the financial domain, it performs only read operations against a public identifier database (Bloomberg OpenFIGI), with no ability to move funds, execute trades, or alter financial obligations.
From the tool's definition Tool maps security identifiers to metadata via OpenFIGI API. Returns FIGI, ticker, exchange, security type, market sector, and description. No data modification, deletion, or financial transactions occur.

Map a security identifier to its FIGI (Financial Instrument Global Identifier) + metadata via OpenFIGI. Give idType (ISIN, CUSIP, SEDOL, TICKER, FIGI, COMMON, WKN, CINS, or raw OpenFIGI ID_* type) and idValue, optionally narrowed by exchCode/currency. Returns each listing with FIGI, composite/share-class FIGI, name, ticker, exchange, security type, market sector, description. Free, open symbology (Bloomberg OpenFIGI). 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: 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 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 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. 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 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.
