Read and analyze a specific NZX announcement. Extracts summary, key figures, sentiment, entities, and risk flags using AI. Provide the announcement_id (e.g. "12345") from search_announcements results. Returns cached results if previously extracted.
AI agents call read_announcement to retrieve information from NZXplorer MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
announcement_id | string | Yes | The announcement_id from search_announcements results |
Parameters from the server's own tool schema.
This tool retrieves and analyzes already-published NZX announcement data. It performs content extraction and NLP analysis on immutable source documents, producing read-only insights. No financial transactions, code execution, data modification, or irreversible actions are possible. The caching behavior is a performance optimization, not a state-changing operation.
From the tool's definition Tool description uses 'Read and analyze' and 'Extracts' language, with no mutation or side-effect verbs. Returns data about announcements (summary, key figures, sentiment, entities, risk flags).

Read and analyze a specific NZX announcement. Extracts summary, key figures, sentiment, entities, and risk flags using AI. Provide the announcement_id (e.g. "12345") from search_announcements results. Returns cached results if previously extracted. It is categorised as a Read tool in the NZXplorer MCP Server MCP Server, which means it retrieves data without modifying state.
read_announcement accepts 1 parameter: announcement_id. Required: announcement_id. The full parameter table on this page comes from the server's own tool schema.
Register the NZXplorer MCP Server MCP server in PolicyLayer and add a rule for read_announcement: 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 NZXplorer MCP Server. Nothing to install.
read_announcement 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 read_announcement 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 read_announcement. 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.
read_announcement is provided by the NZXplorer MCP Server MCP server (mambaventures/nzxplorer-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
