## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-04.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs hatchling.build at install time, a recognised build step with no custom scripting around it.
  - 1 of 31 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 10 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 66/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 574 tokens (~82/item across 7 items; 7 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 53/100
  - Stability observed for 16 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 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.
  - An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (7)

### `add_item` (~105 tokens)

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.

Input parameters:

- `image`
- `key`
- `text`

### `search` (~106 tokens)

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.

Input parameters:

- `image`
- `k` (integer)
- `prefix` (string)
- `query`

### `more_results` (~55 tokens)

The next `k` results of a search (1 to 50), not shown before; empty when none are left.

Input parameters:

- `k` (integer)
- `prefix` (string)
- `query_id` (string, required)

Output parameters:

- `result` (array)

### `score` (~79 tokens)

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.

Input parameters:

- `item_id` (string, required)
- `query_id` (string, required)
- `score` (number, required)

### `delete_item` (~29 tokens)

Delete an item, its content in the index and its scores.

Input parameters:

- `item_id` (string, required)

Output parameters:

- `result` (string)

### `create_grid` (~53 tokens)

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.

Input parameters:

- `name` (string)

### `delete_grid` (~56 tokens)

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.

Input parameters:

- `confirm` (string, required)

Output parameters:

- `result` (string)

## Common questions

### What is the Hashgrid DNA (local) MCP server?

Hashgrid DNA (local) is an MCP server listed in the public MCP registry as ai.hashgrid/sdk. Search that learns from feedback, over text and images: embeds locally, sends DNA only vectors. This page covers its PyPI package (hashgrid).

### Is the Hashgrid DNA (local) MCP server safe to use?

Hashgrid DNA (local) scores 72 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 4 November 2026. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Hashgrid DNA (local) MCP server expose?

Hashgrid DNA (local) exposes 7 tools: add_item, search, more_results, score, delete_item, and 2 more. Their descriptions and schemas cost roughly 483 tokens of context every time the server is loaded.

### Is the Hashgrid DNA (local) MCP server still maintained?

Hashgrid DNA (local) is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Hashgrid DNA (local) MCP server under?

Hashgrid DNA (local) declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
