Category Search and Retrieval
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs hatchling.build at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- 1 of 31 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 10 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability66
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 574 tokens (~82/item across 7 items; 7 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management53
- Stability observed for 16 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "delete_item" implies "delete" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 8 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.

No change was recorded against any check on this day. Stability & Change Management went from 43 to 47. That category is still filling its 30-day observation window: 13 days of observed history at the previous scan, 14 at this one. The score rises as the window fills, whether or not the server changes.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

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 →
add_item ~105
Add an item to search: `text`, or `image`, the path of an image file (images need an image embedder). `key` is a path unique in the grid (e.g. "/docs/intro"), so searches can narrow by prefix; left out, it is a hash of the content, and adding the same content again changes nothing. Returns the item's id and key.
| Name | Type | Req | Description |
|---|---|---|---|
| image | – | – | – |
| key | – | – | – |
| text | – | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
create_grid ~53
Create a DNA grid for this server, when it has none (no key needed): its API key is saved in the local index, and the other tools use it from then on.
| Name | Type | Req | Description |
|---|---|---|---|
| name | string | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
delete_grid ~56
Delete this server's grid, every item and score in it and its content in the local index, for good. `confirm` must be the grid's name. Only when the user asks for it.
| Name | Type | Req | Description |
|---|---|---|---|
| confirm | string | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
delete_item ~29
Delete an item, its content in the index and its scores.
| Name | Type | Req | Description |
|---|---|---|---|
| item_id | string | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
more_results ~55
The next `k` results of a search (1 to 50), not shown before; empty when none are left.
| Name | Type | Req | Description |
|---|---|---|---|
| k | integer | – | – |
| prefix | string | – | – |
| query_id | string | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| result | array | yes | – |
No examples provided.
score ~79
Score how well item `item_id` fits search `query_id`, from -1 (wrong) to 1 (perfect): a result of the search, or any item. Only scores train DNA; a new score replaces the last.
| Name | Type | Req | Description |
|---|---|---|---|
| item_id | string | yes | – |
| query_id | string | yes | – |
| score | number | yes | – |
Structured output declared, but exposes no named fields.
No examples provided.
search ~106
Search the items with a text `query`, or an `image` file: the best `k` (1 to 50) among those whose key starts with `prefix` ("" for any), best first, each with its id, key and text (or image path). Returns them with the `query_id` to pass to more_results and score.
