WHAT IT DOES

What get_facility_risk_delta does on Mcp Server

AI agents call get_facility_risk_delta to retrieve information from Mcp Server 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
`since`	string	—	Look-back window, e.g. "7d" or "30d" (default 7d)
`market`	string	—	Alternatively, a market name or slug (e.g. "northern-virginia")
`facility_id`	string	—	A DC Hub facility id or canonical slug to resolve the market context

Parameters from the server's own tool schema.

RISK

Why get_facility_risk_delta is rated Low

Tool retrieves historical facility risk metrics and temporal analysis without modifying or deleting data.

From the tool's definition Returns DCPI market-health delta, excess-power score change, site-hazard dimensions from history-preserving daily snapshots.

RECOMMENDED RULE

The rule that runs get_facility_risk_delta safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_facility_risk_delta, this is the rule to start with:

get_facility_risk_delta Allowed

get_facility_risk_delta is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Server, apply this rule, and every get_facility_risk_delta call is checked against it from then on.

FAQ

Questions about get_facility_risk_delta

What does the get_facility_risk_delta tool do? +

Use when a user asks what has CHANGED in a facility's (or its market's) risk profile recently — "has this site gotten riskier lately?", "which way is this market moving?" — a temporal question static-trained models can't answer. Returns the REAL DCPI market-health delta (excess-power score change over the window, direction improving/worsening/flat) from DC Hub's history-preserving daily snapshots. INTEGRITY: only DCPI market-health has a short-term temporal series; the site-hazard dimensions (FEMA disaster / USGS seismic / NOAA climate / WRI water) are DECLARED static (they don't change week-to-week) with a pointer to the point-in-time tool — never a fabricated week-over-week delta; no snapshot history → coverage:unavailable. Params: facility_id (a discovered-facility id or slug) OR market (a market name/slug), since (e.g. "7d"/"30d", default 7d). Returns {facility, dcpi_market_health:{delta, now, direction, coverage}, static_dimensions{...}, summary}. For the current point-in-time risk (not the change) use get_composite_site_score / get_disaster_risk / get_climate_intel. It is categorised as a Read tool in the Mcp Server MCP Server, which means it retrieves data without modifying state.

What parameters does get_facility_risk_delta accept? +

get_facility_risk_delta accepts 3 parameters: since, market, facility_id. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on get_facility_risk_delta? +

Register the Mcp Server MCP server in PolicyLayer and add a rule for get_facility_risk_delta: 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 Server. Nothing to install.

What risk level is get_facility_risk_delta? +

get_facility_risk_delta is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit get_facility_risk_delta? +

Yes. Add a rate_limit block to the get_facility_risk_delta 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.

How do I block get_facility_risk_delta completely? +

Set action: deny in the PolicyLayer policy for get_facility_risk_delta. 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.

What MCP server provides get_facility_risk_delta? +

get_facility_risk_delta is provided by the Mcp Server MCP server (https://dchub.cloud/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
