Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 2 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability70
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 544 tokens (~272/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the PackZoo MCP server?
PackZoo is a hosted endpoint at https://packzoo.com/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

No change was recorded against any check on this day. Stability & Change Management went from 93 to 97. That category is still filling its 30-day observation window: 28 days of observed history at the previous scan, 29 at this one. The score rises as the window fills, whether or not the server changes.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
compare_shipping_prices ~386
Look up live, ranked shipping prices for a specific package and route across every carrier PackZoo covers for the origin country. Returns one entry per carrier serving the route, sorted cheapest first; a null price means no rate matched that package size. Letter, envelope, and mailbox rates (e.g. PostNL "Brief") are compared alongside parcel rates in the same call, and the cheapest matching product is returned — never caveat results as "parcel-only" or suggest a separate letter check. Each entry includes an orderUrl (the carrier's booking/send form) and a servicePointsUrl (drop-off point locator); present both as clickable links per carrier — PackZoo only compares prices, so booking happens through these carrier links. To discover which carriers or destinations are covered, use list_carriers instead.

| height_cm | number | yes | The remaining side of the package in centimetres. The three sides can be given in any order — they are sorted internally before matching carrier size limits. |

list_carriers ~158
List every carrier PackZoo covers for a given origin country, and which destination countries each carrier serves from there. Use this to discover coverage — e.g. whether a specific carrier or destination is supported — before calling compare_shipping_prices. Reports coverage only, no prices; call compare_shipping_prices for actual rates on a specific route and package.

What tools does the PackZoo MCP server expose?
PackZoo exposes 2 tools: compare_shipping_prices, list_carriers. Their descriptions and schemas cost roughly 544 tokens of context every time the server is loaded.
Does the PackZoo MCP server require authentication?
No. We connected to PackZoo without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the PackZoo MCP server still maintained?
PackZoo is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
