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 →
Supply Chain Security13
- Malware scan not yet available for this package.Unverified
- Known CVEs could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it.Unverified
- No install/post-install scripts declared.Pass
- Dependency health could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it.Unverified
Provenance & Transparency32
- 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
- License check failed: no license is declared. See how to fix → Fail
- Actively maintained (last published 3 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability74
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 688 tokens (~114/item across 6 items; 6 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage79
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 38% of tool parameters carry a description.Partial
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

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.
forget ~110
Permanently delete documents from memory (purged from disk, not soft-deleted). Requires confirm: true — always ask the user before confirming. time_from/time_to accept ISO 8601 date or datetime, offsets allowed.
| Name | Type | Req | Description |
|---|---|---|---|
| confirm | boolean | yes | – |
| doc_id | integer | – | – |
| source | string | – | – |
| time_from | string | – | ISO 8601 date or datetime, offsets allowed |
| time_to | string | – | ISO 8601 date or datetime, offsets allowed |
No output schema declared.
No examples provided.
get_document ~134
Read a whole document from memory by uri or doc_id — search_memory returns only matching excerpts, so use this when you need the complete text (a full meeting transcript, a whole note). Both uri and doc_id come from search_memory and recent_activity results. Long documents are truncated with an offset footer; call again with that offset to page through the rest.
| Name | Type | Req | Description |
|---|---|---|---|
| doc_id | integer | – | – |
| max_chars | integer | – | – |
| offset | integer | – | character offset into the document |
| source | string | – | disambiguates a uri that exists under more than one source |
| uri | string | – | – |
No output schema declared.
No examples provided.
memory_status ~44
Daemon health: document/vector counts, pending embeddings, model download progress. modelLoaded=false with modelDownloaded=true just means the model is idle-unloaded; it loads on demand.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
recent_activity ~227
Enumerate documents in a time window, in timestamp order. Call this FIRST for vague or broad questions ('what was I working on') to orient, then drill in with search_memory. Unlike search_memory this is NOT ranked by relevance — it returns everything in the window, so it is the right tool for reconstructing a specific period ('what did I do between 13:00 and 16:00 yesterday'). Use time_from/time_to for an explicit past window (ISO 8601, offsets allowed) and order:'asc' to replay a day forwards; `hours` is a lookback-from-now shorthand. Page with limit/offset — the reply says so when more rows remain.
| Name | Type | Req | Description |
|---|---|---|---|
| hours | integer | – | – |
| limit | integer | – | – |
| offset | integer | – | – |
| order | string | – | asc replays a window forwards; default desc |
| sources | array | – | – |
| time_from | string | – | ISO 8601 date or datetime, offsets allowed |
| time_to | string | – | ISO 8601 date or datetime, offsets allowed |
No output schema declared.
No examples provided.
remember ~36
Save an explicit fact or note to the user's local memory for future recall.
| Name | Type | Req | Description |
|---|---|---|---|
| content | string | yes | – |
| tags | array | – | – |
No output schema declared.
No examples provided.
search_memory ~137
Search the user's local memory (files, notes, saved facts) with hybrid keyword+semantic retrieval. The workhorse tool. For vague questions, call recent_activity first to orient, then search with a sharpened query. Resolve relative dates ('last Tuesday') into ISO timestamps yourself via time_from/time_to (ISO 8601 date or datetime, offsets allowed).
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | – |
| query | string | yes | – |
| sources | array | – | – |
| time_from | string | – | ISO 8601 date or datetime, offsets allowed |
| time_to | string | – | ISO 8601 date or datetime, offsets allowed |

What is the shyn MCP server?
shyn is an MCP server listed in the public MCP registry as day.shyn/shyn. Local-first ambient memory for your Mac, pages, meetings, notes, encrypted on-device. This page covers its MCPB bundle (https://github.com/shyn-labs/homebrew-tap/releases/download/v0.4.30-alpha/shyn.mcpb).
Is the shyn MCP server safe to use?
shyn scores 38 out of 100 on VerifyMCP. 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 shyn MCP server expose?
shyn exposes 6 tools: search_memory, recent_activity, get_document, remember, forget, memory_status. Their descriptions and schemas cost roughly 688 tokens of context every time the server is loaded.
