What resolve_entity does on 19hz
AI agents call resolve_entity to retrieve information from 19hz without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
type | string | Yes | Entity type: "company" or "drug". |
value | string | Yes | For company: ticker (AAPL), CIK (0000320193), or name. For drug: brand or generic name (e.g., "ozempic", "metformin"). |
Parameters from the server's own tool schema.
Why resolve_entity is rated Low
This tool performs identifier lookups/resolution against external registries (SEC EDGAR, RxNorm). It only retrieves and returns canonical IDs and metadata — no writes, executions, or destructive actions. Blast radius is minimal as it only reads reference data.
From the tool's definition resolve a user-spoken NAME to the canonical/official identifier other tools require as input
Attacks that exploit this kind of access
The rule that runs resolve_entity safely
PolicyLayer is an MCP gateway: it sits between your AI agents and 19hz, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For resolve_entity, this is the rule to start with:
resolve_entity is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect 19hz, apply this rule, and every resolve_entity call is checked against it from then on.
Questions about resolve_entity
"What's the ticker for…" / "find the CIK for…" / "what's the RxCUI for…" / "look up the ID for…" / "what is X's official identifier" — resolve a user-spoken NAME to the canonical/official identifier other tools require as input. Use FIRST whenever you have a name but need an ID. SUPPORTED TYPES: "company" (returns ticker + 10-digit CIK + company_name from SEC EDGAR + pipeworx://edgar/company/{cik} citation URI; accepts ticker, CIK, or company name as input — auto-disambiguated), "drug" (returns RxCUI + ingredient + brand from RxNorm + pipeworx://rxnorm/{rxcui} citation; accepts brand or generic name). Each call cascades through several lookup endpoints internally — using resolve_entity replaces 2-3 manual lookups. It is categorised as a Read tool in the 19hz MCP Server, which means it retrieves data without modifying state.
resolve_entity accepts 2 parameters: type, value. Required: type, value. The full parameter table on this page comes from the server's own tool schema.
Register the 19hz MCP server in PolicyLayer and add a rule for resolve_entity: 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 19hz. Nothing to install.
resolve_entity 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 resolve_entity 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 resolve_entity. 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.
resolve_entity is provided by the 19hz MCP server (https://gateway.pipeworx.io/19hz/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
