Install

npx — recommended

npx -y @mvanhorn/printing-press-library install shelters

Installs the CLI binary and the agent skill (Claude Code, Codex, Cursor, Gemini CLI, Copilot, and more). Add --cli-only or --skill-only for one half. Requires Node.

Hermes

hermes skills install mvanhorn/printing-press-library/cli-skills/pp-shelters --force

From the Hermes CLI. Inside a chat session use /skills install with the same path.

OpenClaw

Install the pp-shelters skill from https://github.com/mvanhorn/printing-press-library/tree/main/cli-skills/pp-shelters. The skill defines how its required CLI can be installed.

Paste this to your OpenClaw agent — the skill describes how to install its CLI.

Claude Desktop

This CLI ships an MCPB bundle. Download the latest release .mcpb and double-click it — Claude Desktop walks you through the install.

Credible, real-time disaster shelter information for AI agents and people: which FEMA-tracked shelters are open right now, where they are, which take pets, and which are at capacity. Sourced from FEMA's National Shelter System OpenShelters feed, honest about missing data.

Gives agents and people the most credible open-shelter picture straight from FEMA's National Shelter System (NSS) OpenShelters feed: open shelters across all states and territories, who takes pets, who is wheelchair / ADA accessible, and who is filling up. It answers the questions people actually ask in a disaster, like 'the closest open shelter to me that allows pets' and 'which shelters are at capacity', geocoding addresses when the feed omits coordinates and never inventing a number it does not have. Deep thanks to all first responders, emergency management practitioners, and relief nonprofit organizations for the work you do in communities when disaster strikes. This is an unofficial tool; in a life-threatening emergency call 911 and follow the official guidance and evacuation orders from FEMA, your local emergency management, and your local authorities.

Install from source

This repository builds with the Go toolchain (1.26.4 or newer):

go install github.com/mvanhorn/printing-press-library/library/other/shelters/cmd/shelters-pp-cli@latest

Or clone and build the CLI plus the bundled MCP server:

git clone https://github.com/mvanhorn/printing-press-library
cd shelters-pp-cli
make build       # binaries in ./bin
go test ./...    # parsers verified against real + clearly-labeled synthetic fixtures in internal/cli/testdata

Then run shelters-pp-cli doctor (no API key needed) and shelters-pp-cli brief --markdown for a one-call situational briefing.

Install via the Printing Press library

Once this CLI is published to the public library, one command installs both the shelters-pp-cli binary and the pp-shelters agent skill (Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, and other agents supported by the upstream skills CLI):

npx -y @mvanhorn/printing-press-library install shelters

For CLI only (no skill):

npx -y @mvanhorn/printing-press-library install shelters --cli-only

For skill only — installs the skill into the same agents as the default command above, but skips the CLI binary (use this to update or reinstall just the skill):

npx -y @mvanhorn/printing-press-library install shelters --skill-only

To constrain the skill install to one or more specific agents (repeatable — agent names match the skills CLI):

npx -y @mvanhorn/printing-press-library install shelters --agent claude-code
npx -y @mvanhorn/printing-press-library install shelters --agent claude-code --agent codex

Pre-built binary

Download a pre-built binary for your platform from the latest release. On macOS, clear the Gatekeeper quarantine: xattr -d com.apple.quarantine <binary>. On Unix, mark it executable: chmod +x <binary>.

Quick Start

# Confirm the CLI is wired up; no API key needed.
shelters-pp-cli doctor

# What shelters are open right now (few or none when no disaster is active).
shelters-pp-cli shelters

# The closest open shelters to me that allow pets.
shelters-pp-cli near "2400 W Bradley Ave, Champaign, IL" --pets

# One-call situational briefing with the gratitude and safety footer.
shelters-pp-cli brief --markdown

Unique Features

These capabilities aren't available in any other tool for this API.

Closest shelter

near — Ranks open shelters by straight-line distance from a lat,lon, ZIP, or street address; geocodes shelters that are missing coordinates and reports any it cannot locate rather than dropping them.

Answers 'the closest shelter to me that allows pets' in one call; add --pets, --ada, or --wheelchair.
```
shelters-pp-cli near 78566 --pets --limit 3
```

Capacity

capacity — Computes utilization only where both a population and a capacity are reported, labeling the denominator (evacuation vs post-impact), and surfaces shelters reported FULL without asserting it as ground truth.

Answers 'which shelter is at capacity?' honestly, marking unknowns as unknown.
```
shelters-pp-cli capacity --state TX
```

One-call situational awareness

brief — One command returns the open count, a breakdown by state, pet-friendly and accessible counts, and the capacity picture, with an optional human briefing.

Reach for this first when an agent asks 'what is the shelter situation right now'.
```
shelters-pp-cli brief --markdown
```

Listings and detail

shelters — Open shelters flattened from the feed and filterable by state, pets, ADA, wheelchair, managing org, and status.

Use to narrow open shelters to the ones that match a person's needs.
```
shelters-pp-cli shelters --state FL --ada --json
```
shelter — Full detail for one shelter joined on the stable shelter_id rather than the churning objectid, with unreported fields as explicit null.

Use when you have a shelter_id and need its full record.
```
shelters-pp-cli shelter 368133
```

Recipes

Closest pet-friendly shelter as compact JSON for an agent

Shelters confirmed wheelchair accessible in one state

shelters-pp-cli shelters --state TX --wheelchair --json

Which shelters are at or over capacity

shelters-pp-cli capacity --json --select data.shelters

Output Formats

# Human-readable listing (default in terminal, JSON when piped)
shelters-pp-cli shelters

# JSON for scripting and agents
shelters-pp-cli shelters --json

# Filter the inner data to specific fields
shelters-pp-cli shelters --json --select data.count

# Dry run — short-circuit without sending a request
shelters-pp-cli shelters --dry-run

# Agent mode — JSON + compact + no prompts in one flag
shelters-pp-cli shelters --agent

Agent Usage

This CLI is designed for AI agent consumption:

Non-interactive - never prompts, every input is a flag
Pipeable - --json output to stdout, errors to stderr
Filterable - --select returns only the fields you need
Honest - missing data is null or "unknown", never invented
Read-only - this CLI does not create, update, delete, publish, send, or mutate remote resources
Agent-safe by default - no colors or formatting unless --human-friendly is set

Every response carries source and a client-side fetched_at (UTC), because the feed has no server timestamp.

Exit codes: 0 success, 2 usage error, 3 not found, 5 API error, 7 rate limited, 10 config error.

Data, freshness, and honesty

Source: FEMA National Shelter System OpenShelters feed (gis.fema.gov, ArcGIS Feature Service). No API key.
Freshness: NSS reports roughly twice a day and only changes when an emergency manager updates a record, so status can lag reality. The feed carries no timestamp; this CLI stamps each response with the client fetch time.
Empty is normal: a near-empty list means no disaster is active, not a failure. Counts spike during named events.
Coordinates: frequently null even for open shelters; near geocodes from the street address and reports anything it cannot locate.
Capacity: computed only where population and a capacity both exist; the denominator is labeled. Never assumed.
Full NSS (beyond the public OpenShelters feed) requires an MOU with FEMA and is out of scope; gis-links points to it.

Health Check

shelters-pp-cli doctor

Verifies configuration and connectivity to the feed.

Configuration

Config file: ~/.config/shelters-pp-cli/config.toml

Static request headers can be configured under headers; per-command header overrides take precedence.

Troubleshooting

shelters is empty — That is the normal quiet-state contract (no disaster active). It is not an error.
near says a shelter could not be located — The feed omitted coordinates and the address would not geocode; those shelters are reported in a count and excluded from the ranking. Pass a precise lat,lon origin for the most accurate distances.
capacity shows "unknown" for a shelter — The feed did not report both a population and a capacity for it; this tool will not invent a denominator.
