Claude Code: ask. ### `track_package` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Track any parcel by its tracking number. No account needed. Works for parcels shipped through this service with any carrier, and for most Canadian carrier numbers (Canada Post, UPS, FedEx, Purolator, Nationex, GLS). Returns the current status, the estimated or actual delivery date and the carrier's latest scans, plus a link to the full tracking page. Use this whenever someone asks where a parcel is. ``` ### `track_parcel` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Look up the live status and checkpoint history of a parcel on the SIGNED-IN account by its tracking number. Returns the current status, estimated delivery date, the shipment id and the full checkpoint list. Requires the user to connect their account; to track any parcel without signing in, use track_package. Supplying the carrier is optional but makes the lookup faster. ``` ## Only reads (6) Looks things up and changes nothing. Claude Code: allow. ### `compare_shipping_rates` - The name "compare_shipping_rates" says "compare": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "compare" and "post": it reads posts, which other people can write. Description, as the server wrote it: ```untrusted-server-text Compare live shipping rates for one parcel across every carrier available on the SIGNED-IN account (Canada Post, Purolator, UPS, FedEx and others), at the prices of that account. Returns each carrier and service with its total price, currency and estimated transit days. Requires the user to connect their account; for someone without an account use get_shipping_quote, which needs no sign-in. Prices are live and account-specific; do not cache them. ``` ### `find_drop_off_points` - The name "find_drop_off_points" says "find": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Find places near a Canadian postal code where a parcel can be dropped off or picked up. No account needed. Covers Canada Post outlets, FedEx locations, UniUni drop-off points and MesColis counters, nearest first, with the address, distance, what can be done there and a map link. Optionally limit the search to one network. Opening hours vary, so suggest checking the map link before going. ``` ### `get_shipment` - The name "get_shipment" says "get": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Retrieve the full record of a single shipment by its ID, including addresses, carrier, service, cost and current status. ``` ### `get_shipping_quote` - The name "get_shipping_quote" says "get": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "get" and "post": it reads posts, which other people can write. Description, as the server wrote it: ```untrusted-server-text Get live shipping prices for one parcel from several carriers (Canada Post, UPS, FedEx and others). No account needed. Give the origin and destination postal or ZIP codes and the weight in kilograms (convert pounds and inches first); the box size is optional and a 30 x 20 x 10 cm box is assumed when it is missing. Returns up to 6 of the cheapest services with price and estimated transit time, and a link that opens the same quote on the website, where the label can be bought. Prices are the public rates at the moment of the quote. If the user is signed in, compare_shipping_rates returns their own account prices instead. ``` ### `list_addresses` - The name "list_addresses" says "list": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text List saved addresses from the account address book. Read-only — this server cannot create, change or delete addresses. ``` ### `list_shipments` - The name "list_shipments" says "list": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text List shipments on the authenticated account, newest first. Supports paging and filtering by status (for example "Delivered" or "In Transit"). Use get_shipment for the full record of one shipment. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `shipsmarter`: ```json { "permissions": { "allow": [ "mcp__shipsmarter__get_shipping_quote", "mcp__shipsmarter__find_drop_off_points", "mcp__shipsmarter__compare_shipping_rates", "mcp__shipsmarter__list_shipments", "mcp__shipsmarter__get_shipment", "mcp__shipsmarter__list_addresses" ], "ask": [ "mcp__shipsmarter__track_package", "mcp__shipsmarter__track_parcel" ], "deny": [] } } ``` Capability tags behind the rules (a read tagged outbound is asked about): - `mcp__shipsmarter__track_package`: untrusted-input - `mcp__shipsmarter__get_shipping_quote`: untrusted-input - `mcp__shipsmarter__find_drop_off_points`: untrusted-input - `mcp__shipsmarter__compare_shipping_rates`: untrusted-input - `mcp__shipsmarter__track_parcel`: untrusted-input - `mcp__shipsmarter__list_shipments`: untrusted-input - `mcp__shipsmarter__get_shipment`: untrusted-input - `mcp__shipsmarter__list_addresses`: untrusted-input
