## 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 2026-08-03.

- **Supply Chain Security**: 87/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (113 of 114), so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - Only part of the dependency tree could be resolved (113 of 114), so this covers what we could see, not the whole tree.

  - 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 14 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 71/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 702 tokens (~46/item across 15 items; 15 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100

First indexed and scored.

## MCP tools (15)

### `ua_status` (~34 tokens)

Check the operational status of the Understand-Anything MCP server. Call this to verify if the knowledge graph is successfully loaded and active.

### `ua_scan` (~31 tokens)

Check if a knowledge graph file is present and currently loaded. Returns instructions on how to generate the graph if missing.

### `ua_graph_summary` (~33 tokens)

Get a high-level statistical summary of the codebase knowledge graph. Returns total node and edge counts to gauge project size.

### `ua_architecture_report` (~33 tokens)

Generate a module-level architecture report from the knowledge graph. Returns a breakdown of files per directory to identify main components.

### `ua_dependency_report` (~37 tokens)

Generate a top-level dependency report from the knowledge graph. Identifies the most heavily depended-on files in the codebase (high fan-in).

### `ua_explain` (~65 tokens)

Explain a specific part of the codebase by retrieving its 1-hop dependencies. Call this to understand what a file imports and where it is used.

Input parameters:

- `target` (string, required): Required. The precise file path or module name to explain. Example: 'src/core/db.ts'.

### `ua_onboarding_doc` (~32 tokens)

Generate an onboarding overview document for new developers. Call this first when entering a new codebase to get oriented.

### `ua_find_callers` (~84 tokens)

Find all callers of a specific function or file up to a certain depth. Helps trace execution paths.

Input parameters:

- `maxDepth` (number): Optional. Maximum search depth. Defaults to 2 (max 3).
- `target` (string, required): Required. The target file or function ID (e.g., 'src/api/handler.ts' or 'func:processData').

### `ua_impact_analysis` (~52 tokens)

Analyze the downstream impact of changing a specific file. Returns a list of files that depend on it.

Input parameters:

- `target` (string, required): Required. The file being modified (e.g., 'src/core/types.ts').

### `ua_precheck` (~57 tokens)

Pre-flight architectural risk check. Call this before modifying any critical systems or refactoring to estimate risk radius.

Input parameters:

- `target` (string, required): Required. The primary file or module you plan to modify (e.g., 'src/core/db.ts').

### `ua_rules` (~23 tokens)

Evaluate architectural constraints against the current knowledge graph. Generates a full violation report.

### `ua_rules_check` (~24 tokens)

Mid-session continuous audit. Evaluate constraints to ensure recent changes haven't introduced violations.

### `ua_init_rules` (~27 tokens)

Initialize a starter .ua-rules.json file in the workspace if one doesn't already exist.

### `ua_ci_check` (~68 tokens)

Run a CI-style impact analysis on a PR diff to identify risk factors. Returns affected files, risk level, and potential issues.

Input parameters:

- `pr_diff` (string, required): Required. The raw git diff string representing the pull request changes. Must contain '+++ b/' or '--- a/' paths.

### `ua_validate_graph` (~43 tokens)

Validate the structural integrity and syntax of the loaded knowledge graph JSON.

Input parameters:

- `graphData` (string, required): Required. The raw JSON string representation of the knowledge graph to validate.
