The rule that runs list_saved_sites 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 list_saved_sites, this is the rule to start with:
list_saved_sites 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 Mcp Server, apply this rule, and every list_saved_sites call is checked against it from then on.
Questions about list_saved_sites
NEEDS A KEY (free): saved sites are per-account, so a keyless call returns auth_required, not an empty list — if you have no key, call claim_free_key FIRST (one step, no email), then this. Use when a user asks to see or review their saved DC Hub shortlist in-chat, or wants to know what moved on it. Example: "What sites have I saved?" / "Did any of my saved sites move?" — list_saved_sites. Params: since (optional — "24h"/"7d"/ISO, default 7d — the delta window). Returns: each saved site with name, market, lat/lon, saved DCPI score, target MW, notes — PLUS live deltas: verdict_was/verdict_now (e.g. CAUTION → BUILD), excess-power move over the window, current vs at-save DCPI, alerts armed/fired, new facilities nearby, and a portfolio summary flagging which sites moved and which have no alert armed. Do NOT use to add a site (use save_site) or to download the list as a file (use export_dataset); this is the in-chat read-back. It is categorised as a Read tool in the Mcp Server MCP Server, which means it retrieves data without modifying state.
list_saved_sites accepts 1 parameter: since. The full parameter table on this page comes from the server's own tool schema.
