WHAT IT DOES

What save_to_shortlist does on Mcp Server

AI agents use save_to_shortlist to create or update resources in Mcp Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Server environment.

Parameter	Type	Required	Description
`site`	object	Yes	Site object: {site_ref?, lat, lng, capacity_mw, <metric fields from analyze_site>} — the metrics are what get re-scored later
`notes`	string	—	Optional free-text note, e.g. "strong fiber, acceptable water"
`objectives`	object	Yes	The {field: signedWeight} objectives this site was ranked under (+maximize/-minimize) — stored so re-scoring uses the same criteria
`shortlist_name`	string	—	Name of the shortlist, e.g. "Q3-2026-1GW-targets" — created if new

Parameters from the server's own tool schema.

RISK

Why save_to_shortlist is rated Medium

This tool creates and modifies persistent user data (shortlists scoped to an API key) but does not delete, destroy, or cause irreversible changes. It is reversible—items can be removed or lists modified later. It does not execute arbitrary code, move money, or delete data irreversibly.

From the tool's definition Tool description explicitly states it 'Save[s] a site into a PERSISTENT, named shortlist' and 'Snapshots the site's objectives + its current percentile objective_score', indicating creation and modification of user-specific data structures that persist across…

RECOMMENDED RULE

The rule that runs save_to_shortlist 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 save_to_shortlist, this is the rule to start with:

save_to_shortlist Rate-limited

save_to_shortlist stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Save a site into a PERSISTENT, named shortlist that survives across conversations (Phase 5 statefulness). Snapshots the site's objectives + its current percentile objective_score, so you can re-score it later against the evolving national baseline. Use to build a durable siting shortlist across days/weeks; the list is scoped to your API key. Pair with get_shortlist to re-score + see drift. site should carry lat/lng/capacity_mw + the analyze_site metric fields (risk_resilience, fiber_connectivity, water score, etc.) you ranked on. It is categorised as a Write tool in the Mcp Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does save_to_shortlist accept? +
