Category Search and Retrieval
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
- 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- 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 Usability79
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 360 tokens (~120/item across 3 items; 3 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management13
- Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
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
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
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.
- 4 Nov 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

Diagnostic detail from the automated scan of this channel: what the scanner observed at each step, so you can see exactly where a check passed or failed. It is informational only and never changes the trust score.

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 →
get_product Get product ~66
Get one product by id: full description, links, GitHub repository and stars, whether its link responded when last checked, and every reaction with its source, title, number, date, and original discussion URL.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Product id from search_products or similar_products |
| Name | Type | Req | Description |
|---|---|---|---|
| product | object | yes | – |
No examples provided.
search_products Search products ~237
Find existing products launched since ChatGPT's release (Nov 30, 2022) that already do what you need — check here before building something new. Describe the job in short plain English, e.g. "extract tables from PDF to CSV" or "self-hosted dashboard for coding agents"; English works much better than other languages. Results are ranked by relevance (keyword + semantic). Each result has a one-line description, links, forms, an open-source flag, and community reactions labeled by source (e.g. HN 112 pts). Numbers are shown as each source reports them and are never combined; Tangerine Index does not rate products. Use get_product for the full description and every reaction.
| Name | Type | Req | Description |
|---|---|---|---|
| forms | array | – | Only return products that have ALL of these forms |
| limit | integer | – | Maximum number of results (default 8) |
| need | string | yes | What the product should do, as a short plain-English description, e.g. "extract tables from PDF to CSV" |
| open_source | boolean | – | true: only open-source products (GitHub repositories); false: only the others |
| Name | Type | Req | Description |
|---|---|---|---|
| note | string | – | Present when results are limited, e.g. semantic search unavailable |
| results | array | yes | – |
No examples provided.
similar_products Similar products ~57
List up to 5 products whose descriptions are closest to the given product's description. Similarity is by description embedding only — not quality, popularity, or recency.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Product id from search_products or similar_products |
| Name | Type | Req | Description |

| basis | string | yes | – |

How do I install the Tangerine Index MCP server?
Tangerine Index is a hosted endpoint at https://tangerineindex.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.
