Look up one EPA-regulated facility by its FRS Registry ID. Returns the facility detail plus a programs[] array listing every EPA program (RCRAINFO, NPDES, AIRS, TRI, etc.) the site is regulated under. Keyless.
AI agents call get_facility to retrieve information from Mcp Epa Envirofacts without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |

Parameters from the server's own tool schema.
This tool retrieves environmental facility information from a public EPA database. It performs a lookup operation without side effects—no data is created, modified, deleted, or executed. The 'Keyless' notation suggests open access to public environmental records. The blast radius of misuse is minimal since the data returned is public regulatory information already available through EPA channels.
From the tool's definition Tool description specifies 'Look up' and 'Returns' facility data and program information. The keyless access and read-only nature of querying existing EPA registry data indicates pure data retrieval with no modification or deletion capability.

Look up one EPA-regulated facility by its FRS Registry ID. Returns the facility detail plus a programs[] array listing every EPA program (RCRAINFO, NPDES, AIRS, TRI, etc.) the site is regulated under. Keyless. It is categorised as a Read tool in the Mcp Epa Envirofacts MCP Server, which means it retrieves data without modifying state.
get_facility accepts 1 parameter: registry_id. Required: registry_id. The full parameter table on this page comes from the server's own tool schema.
Register the Mcp Epa Envirofacts MCP server in PolicyLayer and add a rule for get_facility: 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 Mcp Epa Envirofacts. Nothing to install.
get_facility 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_facility 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 get_facility. 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.
get_facility is provided by the Mcp Epa Envirofacts MCP server (pipeworx-io/mcp-epa-envirofacts). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
