AI agents call find_tool to retrieve information from Ainumbers Mcp Apps without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
query | string | Yes | Natural-language or keyword search (e.g. "FRTB", "XVA", "MiCA own funds", "AML risk rating", "stress test"). |

Parameters from the server's own tool schema.
This is a search/discovery utility that retrieves read-only metadata from a tool catalog. It has no side effects, cannot modify data, and poses minimal risk even if misused—an agent might search for the wrong tool but cannot cause harm through the search itself. Classification as Read is appropriate.
From the tool's definition Tool performs 'BM25 search' and 'Returns ranked tools' - a query operation that retrieves and ranks metadata about available tools. The description explicitly states it locates tools without executing them ('before calling it').

BM25 search over all 216 live AINumbers ChainGraph node tools. Returns ranked tools with mcp_name, URL, mandate type, and wave. Use to locate a specific computation node (e.g. "FRTB expected shortfall", "MiCA own funds", "XVA calculator") before calling it. Complements find_chain (chain-level) and list_ainumbers_tools (catalog-level). It is categorised as a Read tool in the Ainumbers Mcp Apps MCP Server, which means it retrieves data without modifying state.
find_tool accepts 2 parameters: query, top_n. Required: query. The full parameter table on this page comes from the server's own tool schema.
Register the Ainumbers Mcp Apps MCP server in PolicyLayer and add a rule for find_tool: 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 Ainumbers Mcp Apps. Nothing to install.
find_tool 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 find_tool 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 find_tool. 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.
find_tool is provided by the Ainumbers Mcp Apps MCP server (postoaklabs/ainumbers-mcp-apps). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
