geocode_address
Geocode a US street address with the Census Geocoder (keyless). Accepts a one-line address OR structured street/city/state/zip parts. Returns the normalized matched address, longitude/latitude, and Census geographies (state, county, tract, block, congressional district) with GEOIDs. No match retu...

What geocode_address does on Livedatalink
AI agents call geocode_address to retrieve information from Livedatalink 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 |
|---|---|---|---|
zip | string | — | ZIP code for a structured query. |
city | string | — | City for a structured query. |
state | string | — | Two-letter state code for a structured query (e.g. 'DC'). |
street | string | — | Street line for a structured query (e.g. '4600 Silver Hill Rd'). |
address | string | — | One-line address, e.g. '4600 Silver Hill Rd, Washington, DC 20233'. Provide this OR the structured parts. |
Parameters from the server's own tool schema.
Why geocode_address is rated Low
Even though geocode_address only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs geocode_address safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Livedatalink, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For geocode_address, this is the rule to start with:
geocode_address 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 Livedatalink, apply this rule, and every geocode_address call is checked against it from then on.
Questions about geocode_address
Geocode a US street address with the Census Geocoder (keyless). Accepts a one-line address OR structured street/city/state/zip parts. Returns the normalized matched address, longitude/latitude, and Census geographies (state, county, tract, block, congressional district) with GEOIDs. No match returns an explicit not-found message. It is categorised as a Read tool in the Livedatalink MCP Server, which means it retrieves data without modifying state.
geocode_address accepts 5 parameters: zip, city, state, street, address. The full parameter table on this page comes from the server's own tool schema.
Register the Livedatalink MCP server in PolicyLayer and add a rule for geocode_address: 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.
geocode_address 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 geocode_address 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 geocode_address. 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.
geocode_address 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.
