PackRat

Quickstart

PackRat is a custom connector in Claude.ai. The install:

In Claude.ai, open Settings → Connectors → Add custom connector.
Paste the connector URL: https://mcp.packratai.com/mcp
Claude redirects you to PackRat to sign in. You'll briefly see api.packrat.world in your browser address bar — that's our authorization server, hosted on a separate origin from the MCP endpoint for security (a standard OAuth 2.1 + PKCE split-host pattern). Sign in with your PackRat account, or create one at packratai.com.
Approve the requested scopes on the consent screen. Claude requests mcp:read and mcp:write by default. You can approve all, deny, or (in a future release) approve a subset. mcp:admin is only granted server-side based on your PackRat user role — non-admins never see it offered.
You're returned to Claude.ai. The connector is now installed and the tool catalog is loaded.

Tokens are short-lived (60 minutes) and refresh automatically. Revoke the connection at any time from your PackRat account settings or by emailing [email protected].

If your install fails…

The cross-origin install above depends on Claude.ai's OAuth discovery client correctly following the link from the MCP resource server to the authorization server. A handful of failure modes can show up:

“Could not connect” or a CORS error in the browser console. The browser blocked Claude's probe of the authorization-server metadata. Verify api.packrat.world is reachable from your network and not filtered by a corporate proxy / VPN.
Sign-in succeeds but you bounce back to Claude with an error. Some browser extensions strip the Authorization header on cross-origin redirects. Try a fresh browser profile or disable third-party cookie restrictions for claude.ai + api.packrat.world.
The consent screen shows the wrong client name. Claude.ai has been pre-registered with the AS, so “Claude” should appear as the requesting app. If you see unknown or a different name, the install is pointed at the wrong URL — confirm you pasted https://mcp.packratai.com/mcp exactly.
Tools work for ~60 minutes then stop. Refresh-token rotation failed. Remove the connector in Claude.ai's settings and re-add it; if it recurs, email [email protected] with the timestamp and we'll check the AS logs.

Operators: deeper failure modes (including the reverse-proxy fallback for cross-origin AS issues) are in docs/mcp/runbook.md § Post-refactor dev verification.

OAuth scopes

PackRat advertises four coarse-grained scopes. Claude.ai requests mcp:read + mcp:write by default; mcp:admin is only granted to PackRat admin users and is the gate for destructive admin tooling.

Scope	Grants
`mcp:read`	Read-only tools: get_, list_, search_, find_, whoami.
`mcp:write`	Read plus create/update/delete/submit tools.
`mcp:admin`	Read + write + admin tools. Only granted to PackRat admin users.

Example prompts

Three prompts to try after connecting. Each exercises a different tool surface — a read-only query, a multi-tool plan, and a write that triggers an elicitation confirmation.

Read-only · packs & gear comparison

“What's in my Big 3 right now? Suggest one swap to drop a pound.”

Exercises packrat_list_packs, packrat_list_pack_items, packrat_similar_pack_items. Claude reads your current pack, finds the three heaviest items (shelter, sleep, pack), and proposes a single lighter substitute from the gear catalog.

Multi-tool plan · trip + weather + trail status + pack

“Plan a 3-day trip to the Wind River Range next weekend; build the pack, check the weather, and flag any trail closures.”

Exercises packrat_search_trails, packrat_get_weather, packrat_list_my_trail_reports, packrat_create_trip, packrat_create_pack. Claude composes a trip with the right gear for the forecast and surfaces any user-reported closures along the route.

Write with elicitation · TikTok URL → personal pack template

“Find a TikTok ultralight loadout I saw at <url> and import it as a personal template.”

Exercises packrat_extract_url_content and packrat_generate_pack_template_from_url (admin-only — for non-admin users, Claude falls back to packrat_create_pack_template). The tool triggers an MCP elicitation asking you to type GENERATE before importing — this is the user-confirmation pattern Anthropic's reviewers should see firing on high-blast-radius writes.

Tool catalog

The connector exposes 93 tools grouped into 14 domains: 41 read-only, 26 write, 26 admin. Each tool carries explicit MCP annotations (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) so Claude can surface the right confirmation prompts.

Catalog list views and resource lists are capped at 25 items to keep context lean; reach deeper with packrat_search_gear_catalog.

Catalog generated 2026-08-29 from the live registration code — see packages/mcp/scripts/dump-catalog.ts.

Resources

PackRat publishes six MCP resources alongside the tool catalog. Templated resources carry list providers so MCP clients can enumerate the signed-in user's data via resources/list without guessing IDs.

packrat://packs/{packId} — a pack and its items. List provider returns the user's packs.
packrat://trips/{tripId} — a trip's plan, destination, and dates. List provider returns the user's trips.
packrat://catalog/{itemId} — a gear catalog item. List provider returns the first 25 items (use packrat_search_gear_catalog for deeper access).
packrat://catalog/categories — the gear category tree.
packrat://search?q={query} — free-text query against the gear catalog.
packrat://glossary — domain vocabulary (pack/trip/weight/trail/scope terms) as markdown. Reading this once at session start saves Claude tool calls re-learning terminology.

Privacy & security

Tokens. OAuth access tokens are short-lived JWTs (60 minutes) signed by our authorization server on api.packrat.world. Refresh tokens last 30 days and rotate on every use. Token state is held on the authorization-server side; the MCP endpoint itself is stateless and verifies tokens against the AS's public JWKS.
Passwords. Your PackRat password is never visible to the MCP client; sign-in happens entirely on api.packrat.world and only an opaque OAuth code is returned to Claude.
Conversations. We do not log the conversation content you send to MCP clients — only the tool calls those clients make against PackRat.
Audience-bound tokens. Per RFC 8707, every issued access token is bound to https://mcp.packratai.com/mcp so a stolen token can't be replayed against another service.

Read the full MCP section of the privacy policy, the terms of service, or email [email protected] for support.

Reviewer test account

Anthropic reviewers: test-account credentials are provided separately via the submission form. The packet doc (docs/mcp/submission-packet.md in the PackRat repo) lists what's populated in the account: a few packs with realistic items, a sample multi-day trip, and a public feed post. First-run instructions are in the same doc.

We do not publish credentials on this page.
