Available components
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 Security86
- No malware found by supply-chain analysis.Pass
- Only part of the dependency tree could be resolved (94 of 98), so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- Only part of the dependency tree could be resolved (94 of 98), so this covers what we could see, not the whole tree. 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 36 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability44
- 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Fail
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 710 tokens (~118/item across 6 items; 5 tools + 1 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 Management27
- Stability observed for 8 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
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

First indexed and scored.
Diagnostic detail from the automated scan of this channel: what the scanner observed at each step, so you can see exactly where a check passed or failed. It is informational only and never changes the trust score.

The dependency tree was only partially resolved, so these counts may be incomplete.
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.
memory_bridge ~130
Create a cross-bank memory bridge (tunnel) between two related memories in different banks. Relations: same_concept, depends_on, contradicts, extends. Use when concepts in separate banks are related.
| Name | Type | Req | Description |
|---|---|---|---|
| confidence | number | — | Confidence score 0.0–1.0 (default: 0.8) |
| relation | string | yes | Relationship type |
| source_bank | string | yes | Source bank ID |
| source_memory | string | yes | UUID of the source memory |
| target_bank | string | yes | Target bank ID |
| target_memory | string | yes | UUID of the target memory |
No output schema declared.
No examples provided.
memory_compress ~134
Create compressed memory summaries (closets) from stored facts. Groups memories by room+hall and creates AI-generated summaries with source pointers. Use when a topic has accumulated many facts.
| Name | Type | Req | Description |
|---|---|---|---|
| bank_id | string | — | Memory bank ID (default: mempalace-main) |
| hall | string | — | Knowledge type to compress (e.g. "fact", "decision") |
| min_sources | number | — | Min memories needed to create a closet (default: 5) |
| query | string | — | Query to guide compression focus |
| room | string | — | Topic to compress (e.g. "auth", "pipeline") |
No output schema declared.
No examples provided.
memory_recall ~140
Search long-term memory for relevant facts. Uses semantic search with optional room/hall scoping for significantly improved retrieval accuracy. Supports layer cascade (L0 results always prioritized).
| Name | Type | Req | Description |
|---|---|---|---|
| bank_id | string | — | Memory bank ID (default: mempalace-main) |
| hall | — | — | Filter by hall(s): fact, event, decision, etc. |
| limit | number | — | Max results (default: 10) |
| max_layer | string | — | Max layer depth to search (default: L3 = all) |
| query | string | yes | What to search for in memory |
| room | — | — | Filter by room(s) — applied before semantic search |
No output schema declared.
No examples provided.
memory_reflect ~80
Deep reasoning over memory — synthesizes facts, finds patterns, answers complex questions with citations. Use for analysis: "What patterns emerge from recent events?" or "Summarize everything about X."
| Name | Type | Req | Description |
|---|---|---|---|
| bank_id | string | — | Memory bank ID (default: mempalace-main) |
| query | string | yes | Question to reason about over stored memories |
No output schema declared.
No examples provided.
memory_retain ~221
Save a fact, observation, or document to long-term memory with automatic room/hall classification. Rooms: auth, pipeline, schema, infrastructure, ui, api, deployment, monitoring, agent, general. Halls: fact, event, decision, preference, discovery, procedure, warning. Layers: L0=Identity (always loaded), L1=Critical, L2=Session (default), L3=Deep.

| bank_id | string | — | Memory bank ID (default: mempalace-main) |
| context | string | — | Context label (e.g. "meeting notes", "client call") |
| document_id | string | — | Document ID to group related facts |
| hall | string | — | Knowledge type (auto-classified if omitted) |
| layer | string | — | Priority layer (default: L2) |
| room | string | — | Topic room (auto-classified if omitted) |
