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 Security77
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability55
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 548 tokens (~548/item across 1 items; 1 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 Management20
- Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage95
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 86% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 1 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
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 5 Nov 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 17 to 20. That category is still filling its 30-day observation window: 5 days of observed history at the previous scan, 6 at this one. The score rises as the window fills, whether or not the server changes.
- 3 Nov 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 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 →
catalog.search Search independent shops ~351
Search shops that publish a signed Agent Card, plus shops listed from public data (provenance "unclaimed": search-only, no door). Shops are listed by how well their PRODUCTS match, best first; demo stores, wholesalers, off-topic sellers and non-shop sites (reviews, how-to, repair, coupons, with no known price) are left out and counted in `filtered`. Each result gives the shop's origin, DID, Agent Card URL and its best matching products (name, price, link, image when the shop is signed or claimed), so an agent can go straight to that shop's Agent Entry with a signed request. Without `limit` the answer is the top 5 shops with 3 products each (`more` says how many further shops matched); pass `limit` for more shops, or use GET /catalog/search for the full rows.
| Name | Type | Req | Description |
|---|---|---|---|
| in_stock | boolean | – | true: only in-stock products, and only shops that have one. |
| limit | integer | – | – |
| max_price | number | – | Keep products whose known price (a fixed price, or the low end of a range) is at most this, in the shop's currency. A product with an unknown price never passes. |
| q | string | – | Words to match in shop cards and products. |
| sort | string | – | "price": each shop's products cheapest first, unknown prices last. |
| tags | array | – | Keep shops whose card skills carry ALL of these tags. |
| unfiltered | boolean | – | Operators only. true: also list the shops the relevance filters leave out (demo/sample stores, wholesalers, off-topic sellers, non-shop sites); `filtered` counts them otherwise. |

How do I install the Muretai Catalog MCP server?
Muretai Catalog is a hosted endpoint at https://catalog.muretai.com/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.
