## 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 2026-09-20.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **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 40 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 82/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 339 tokens (~67/item across 5 items; 5 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 87/100
  - Stability observed for 26 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "forget_memory" implies "delete" and declares no destructiveHint at all, which the MCP spec reads as destructive by default.
  - An AI judge read all 6 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 (5)

### `index_info` (~47 tokens)

Show metadata (metric, dimensions, size) for a memory index key.

Input parameters:

- `key` (string, required): The index key, e.g. mem:text-embedding-3-small:cosine

### `store_memory` (~69 tokens)

Persist a fact or piece of text to long-term memory. Use this whenever the user asks you to remember, save, note, or keep something for later — it stores the text durably in Garnet so it can be recalled in future sessions.

Input parameters:

- `text` (string, required): The text to remember

### `forget_memory` (~33 tokens)

Delete a stored memory by its id (returned from store_memory).

Input parameters:

- `id` (string, required): The memory id to delete

### `list_indexes` (~18 tokens)

List the vector-set memory indexes that currently exist.

### `recall_memory` (~79 tokens)

Look up previously stored memories by meaning (semantic search). Use this to answer questions about what the user told you to remember earlier — prefer it over relying on the current conversation, since memories persist across sessions.

Input parameters:

- `query` (string, required): What to search for
- `topK` (integer): How many results to return (optional, default 5)

## Common questions

### What is the garnet-mcp server?

garnet-mcp is listed in the public MCP registry as io.github.tarazou9/garnet-mcp. RAG memory for LLM agents over Garnet Vector Sets: store text as embeddings, recall by meaning. This page covers its NuGet package (GarnetMcp.Server).

### Is the garnet-mcp server safe to use?

garnet-mcp scores 82 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026. It declares no install or post-install scripts. 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 garnet-mcp server expose?

garnet-mcp exposes 5 tools: index_info, store_memory, forget_memory, list_indexes, recall_memory. Their descriptions and schemas cost roughly 246 tokens of context every time the server is loaded.

### Is the garnet-mcp server still maintained?

garnet-mcp 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.

### What licence is the garnet-mcp server under?

garnet-mcp declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
