WHAT IT DOES

What list_saved_sites does on Mcp Server

AI agents call list_saved_sites 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	—	Delta window for per-site movement: "24h", "7d" (default) or an ISO-8601 timestamp — pass your cached generated_at from last session

Parameters from the server's own tool schema.

RISK

Why list_saved_sites is rated Low

list_saved_sites performs a pure query operation that retrieves existing user data (saved data center sites, scores, and comparative deltas) without creating, modifying, deleting, or executing operations. The tool only presents information to the user. No side effects, no state changes, no external triggering. This is clearly a Read category tool with low blast radius if misused by an agent.

From the tool's definition Tool retrieves and queries saved sites and their metadata (name, market, coordinates, scores, notes) and live deltas; returns data without modification or side effects. Verbs: 'list', 'see', 'review', 'returns' indicate read-only retrieval operations.

RECOMMENDED RULE

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 Allowed

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

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_saved_sites": {}
  }
}

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 list_saved_sites call is checked against it from then on.

FAQ

Questions about list_saved_sites

What does the list_saved_sites tool do? +

Use when a user asks to see or review their saved DC Hub shortlist in-chat (FREE with a key), 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.

What parameters does list_saved_sites accept? +

list_saved_sites accepts 1 parameter: since. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on list_saved_sites? +

Register the Mcp Server MCP server in PolicyLayer and add a rule for list_saved_sites: 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 list_saved_sites? +

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

Can I rate-limit list_saved_sites? +

Yes. Add a rate_limit block to the list_saved_sites 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 list_saved_sites completely? +

Set action: deny in the PolicyLayer policy for list_saved_sites. 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 list_saved_sites? +

list_saved_sites 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.
