Retrieve employment data across all available years for a single area. Returns an array of yearly metrics (total jobs, industry mix, earnings, age breakdown) ordered ascending by year. Use 'perspective' to choose workplace (default) or residence.
AI agents call get_employment_trend to retrieve information from loc8n Geographic Data without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
geoid | string | Yes | FIPS code for the area — 11 digits for tract, 5 for county, 2 for state. |

Parameters from the server's own tool schema.
This tool queries historical employment trend data for a geographic area and returns metrics without creating, modifying, deleting, or executing anything. It has no side effects beyond data retrieval. The 'perspective' parameter only changes which dimension of existing data is returned, not the data itself. Blast radius of misuse is limited to information disclosure of public demographic/employment statistics.
From the tool's definition Tool 'retrieves employment data' and 'returns an array of yearly metrics' with no mention of modification, deletion, or execution capabilities. The verb 'Retrieve' and the output-only nature indicate a read operation.

Use 'perspective' to choose workplace (default) or residence. It is categorised as a Read tool in the loc8n Geographic Data MCP Server, which means it retrieves data without modifying state.
get_employment_trend accepts 3 parameters: geoid, area_type, perspective. Required: geoid, area_type. The full parameter table on this page comes from the server's own tool schema.
Register the loc8n Geographic Data MCP server in PolicyLayer and add a rule for get_employment_trend: 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 loc8n Geographic Data. Nothing to install.
get_employment_trend 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 get_employment_trend 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.
