Category Memory and Knowledge
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
- 0 of 1 dependencies flagged as unhealthy. View diagnostics → Pass
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to meridian21lab/cogito-mem). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 0 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability68
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 472 tokens (~236/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management7
- Stability observed for 2 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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 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 supported MCP spec version (2025-11-25); the latest is 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.
- 22 Oct 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

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 →
memory_append Save to memory ~91
Save a note to the user's long-term memory: an idea, a decision, an open question or a fact the user stated. Write it so it makes sense on its own later. It is stored word for word with the current time and cannot be edited.
| Name | Type | Req | Description |
|---|---|---|---|
| text | string | yes | The note, word for word. |
| title | string | – | Optional short title, e.g. the project or topic. |
No output schema declared.
No examples provided.
memory_query Search memory ~232
Search the user's long-term memory of earlier chats and sessions. Returns the few stored messages that best match, each with valid_at (when it was said) and a source pointing to the original message. Turn time phrases into valid_after (inclusive) and valid_before (exclusive): for 'a week ago' use a window of a few days around that date, for 'last month' that month. Today is Wednesday 2026-10-21 (UTC); the response's as_of is the current time.
| Name | Type | Req | Description |
|---|---|---|---|
| max_tokens | integer | – | Reading budget for the returned text, in tokens (default 1000). |
| text | string | yes | What to look for, in the user's own words. |
| valid_after | string | – | Only items said at or after this RFC 3339 time with a time zone, e.g. 2026-10-11T00:00:00Z. |
| valid_before | string | – | Only items said before this RFC 3339 time with a time zone, e.g. 2026-10-11T00:00:00Z. |
No output schema declared.
