AI agents use ticker_resolve to create or modify resources in Drillr — The financial MCP for AI agents. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call ticker_resolve repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Drillr — The financial MCP for AI agents.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Resolve a company name, brand, or ticker substring to canonical ticker(s). Use this FIRST when the user mentions a company by name/brand/nickname before running any ticker-keyed tool. Input: - query (required): company name, brand, or ticker substring, e.g. "Apple", "苹果", "AAPL", "OpenAI" - market (optional): "us" | "jp" — omit to search both markets Returns up to 5 matches ranked by prefix-hit first, then name length.. It is categorised as a Write tool in the Drillr — The financial MCP for AI agents MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Drillr — The financial MCP for AI agents MCP server in PolicyLayer and add a rule for ticker_resolve: 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 Drillr — The financial MCP for AI agents. Nothing to install.
ticker_resolve is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the ticker_resolve 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 ticker_resolve. 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.
ticker_resolve is provided by the Drillr — The financial MCP for AI agents MCP server (https://gateway.drillr.ai/mcp/data). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
