AI agents use entity_resolve to create or modify resources in Livedatalink. 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 entity_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 Livedatalink.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Resolve a company across US government sources in one call. Searches SEC EDGAR, EPA ECHO, and the sanctions lists by name and returns the candidate match and strong identifiers (SEC CIK, ticker, EPA registry id) found in each. Use this to confirm WHO an entity is and gather its IDs before pulling detail. Matches are name-based candidates to verify, not certain identity links.. It is categorised as a Write tool in the Livedatalink MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Livedatalink MCP server in PolicyLayer and add a rule for entity_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 Livedatalink. Nothing to install.
entity_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 entity_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 entity_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.
entity_resolve is provided by the Livedatalink MCP server (https://livedatalink.ai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
