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 Security13
- Malware scan not yet available for this package.Unverified
- Known CVEs could not be checked: the version this server declares is not published in its registry.Unverified
- No install/post-install scripts declared.Pass
- Dependency health could not be checked: the version this server declares is not published in its registry.Unverified
Provenance & Transparency71
- Repository check failed: the declared repository URL redirects; it must resolve directly. See how to fix → View diagnostics → Fail
- Cryptographically verified build provenance (signed, bound to GhostPawJS/codex). 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 Usability72
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1118 tokens (~159/item across 7 items; 7 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 Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
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 7 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (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.
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.

Background: How many MCP packages publish verified provenance →
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 →
dismiss_proximity ~123
Record that two beliefs are not meaningfully related despite proximity detection. Uses exponential backoff — the pair will resurface less frequently with each dismissal. Use when: Use this after inspecting two proximate beliefs and determining they are not duplicates or in conflict. The dismissal suppresses the pair in future proximity results. Not for: Do not use this if the beliefs are genuinely related — instead use revise_belief to merge, correct, or forget one of them.
| Name | Type | Req | Description |
|---|---|---|---|
| beliefA | integer | yes | First belief id. |
| beliefB | integer | yes | Second belief id. |
No output schema declared.
No examples provided.
inspect_codex_item ~113
Inspect one belief in full detail: certainty, freshness, strength, source, category, lineage chain, proximity to similar beliefs, and version diff when applicable. Use when: Use this after finding a belief through search_codex or review_codex to understand it deeply before deciding whether to confirm, correct, or forget it. Not for: Do not use this for bulk browsing — use review_codex for lists. Do not call this without a specific belief id.
| Name | Type | Req | Description |
|---|---|---|---|
| beliefId | integer | yes | Belief identifier. |
No output schema declared.
No examples provided.
remember_belief ~156
Create a new belief from a claim, source, and category. Automatically detects nearby beliefs for duplicate awareness. Use when: Use this when a new proposition should enter the codex. Always search first to check whether the belief already exists — prefer confirming or correcting an existing belief over creating a duplicate. Not for: Do not use this to update an existing belief. Use revise_belief with the correct, confirm, or merge action instead.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | yes | What kind of claim. |
| certainty | number | – | Optional initial certainty 0–1. |
| claim | string | yes | The proposition being asserted. |
| provenance | string | – | Optional origin reference. |
| source | string | yes | Where the belief came from. |
No output schema declared.
No examples provided.
retire_belief ~110
Permanently delete a belief and its entire lineage chain. No trace remains. This is for privacy and hard erasure, not normal revision. Use when: Use this only for privacy cleanup or hard erasure. The belief and all of its lineage (predecessors and successors) will be destroyed. Not for: Do not use this for normal belief lifecycle — use revise_belief with the forget action to preserve the audit trail.
| Name | Type | Req | Description |
|---|---|---|---|
| beliefId | integer | yes | Belief id to delete. |
No output schema declared.
No examples provided.
review_codex ~154
Load a codex review surface: flags for beliefs needing attention, status for portfolio health, log for recent activity, or trends for time-based patterns. Use when: Use this when you need an overview of the codex state rather than a specific belief. Start with flags for maintenance, status for a dashboard, or log for recent changes. Not for: Do not use this to find a specific belief by topic — use search_codex instead. Do not use this to inspect one belief deeply — use inspect_codex_item.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Maximum entries for the log view. |
| now | integer | – | Optional timestamp override for freshness computation. |
| view | string | yes | Which codex review surface to load. |
No output schema declared.
No examples provided.
revise_belief ~230
Revise an existing belief: confirm it still holds, correct it with a new claim, merge multiple beliefs into one, forget it from active recall, or defer its next flag review. Use when: Use this after inspecting a belief to act on it. Choose the action that matches the situation: confirm for reinforcement, correct for changed understanding, merge for consolidation, forget for removal from active recall, defer for postponing review. Not for: Do not use this to create a new belief — use remember_belief. Do not use this to permanently delete a belief — use retire_belief.
| Name | Type | Req | Description |
|---|---|---|---|
| action | string | yes | Revision action. |
| beliefId | integer | – | Single belief id. |
| beliefIds | array | – | Belief ids for merge. |
| category | string | – | Optional replacement category. |
| certainty | number | – | Optional certainty override. |
| claim | string | – | Replacement or merged claim. |
| deferredUntil | integer | – | Future timestamp for deferred review. |
| source | string | – | Optional replacement source. |
| successorId | integer | – | Existing active successor belief id. |
No output schema declared.
No examples provided.
search_codex ~133
Search active beliefs by natural language query. Returns ranked matches with recall scores and transparency metadata. Use when: Use this to find beliefs about a topic before acting on them. Always search before creating a new belief to avoid duplicates. Not for: Do not use this for browsing all beliefs — use review_codex with the status or flags view instead.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Optional category filter. |
| limit | integer | – | Maximum number of results. |
| minScore | number | – | Minimum recall score threshold. |
| query | string | yes | Free-form natural language query. |
| source | string | – | Optional source filter. |
No output schema declared.
