## 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**: 86/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (94 of 98), 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 (94 of 98), so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 45/100
  - 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 74 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 70/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 522 tokens (~130/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - 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
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

First indexed and scored.

## MCP tools (4)

### `query_log_pattern` (~118 tokens)

Filter NDJSON log file by field/value pattern, return top N matching entries.

Input parameters:

- `field` (string, required): JSON field name to filter on (e.g. 'level', 'service')
- `limit` (integer): Max entries to return
- `lineStartPattern` (string): Regex that marks new log line start (e.g. "^{") — enables multiline stack trace reconstruction
- `logFile` (string, required): Absolute path to the NDJSON log file
- `value` (string, required): Value to match (case-insensitive substring)

### `detect_error_anomalies` (~135 tokens)

Z-score frequency analysis to find sudden error spikes by time window.

Input parameters:

- `errorValues` (array): Level values to treat as errors
- `levelField` (string): Field containing log level
- `lineStartPattern` (string): Regex that marks new log line start — enables multiline stack trace buffering
- `logFile` (string, required): Absolute path to the NDJSON log file
- `timestampField` (string): Field containing ISO timestamp
- `windowMinutes` (integer): Aggregation window size in minutes
- `zScoreThreshold` (number): Z-score threshold above which a window is flagged as anomalous

### `summarize_log_timeline` (~140 tokens)

Chronological severity aggregation — errors, warnings, and info counts per time window.

Input parameters:

- `adaptive` (boolean): Auto-scale bucket size to actual event density — samples first 1000 events to choose ms/s/min granularity and zooms in on the peak error window
- `levelField` (string): Field containing log level
- `lineStartPattern` (string): Regex that marks new log line start — enables multiline stack trace buffering
- `logFile` (string, required): Absolute path to the NDJSON log file
- `timestampField` (string): Field containing ISO timestamp
- `windowMinutes` (integer): Aggregation window size in minutes

### `correlate_request` (~129 tokens)

Reconstruct a distributed trace by collecting all log events matching a trace/request ID across multiple NDJSON files, sorted chronologically.

Input parameters:

- `idField` (string): Field name containing the trace/request ID
- `lineStartPattern` (string): Regex that marks new log line start — enables multiline stack trace buffering
- `logFiles` (array, required): Array of absolute paths to NDJSON log files
- `serviceField` (string): Field name for service/component name
- `timestampField` (string): Field name for ISO timestamp
- `traceId` (string, required): Trace/request ID value to search for
