## 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 (95 of 99), 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 (95 of 99), 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 98 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 395 tokens (~131/item across 3 items; 3 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 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 (3)

### `normalize_trace` (~149 tokens)

Coerce an arbitrary tool-call trace (an array of {name,args} entries or a partial Trace object) into the canonical agentsnap Trace shape. Returns the normalized trace plus a SHA-256 fingerprint hash computed over the canonical (key-sorted) JSON, so two runs can be byte-compared cheaply.

Input parameters:

- `input` (string): Optional input string to embed in trace.input.
- `model` (string): Optional model identifier to embed in trace.model.
- `output` (string): Optional output string to embed in trace.output.
- `trace` (required): Either an array of tool-call entries (each {name, args, result?, error?}) or a partial Trace object with a tools[] field.

### `diff_traces` (~163 tokens)

Diff two normalized agentsnap traces and surface meaningful differences. Returns same=true on a structural match, otherwise lists additions (paths only present in current), removals (paths only present in baseline), and changes (paths whose values differ). Use ignore_paths to drop noisy fields (e.g. ["fingerprint","tools[0].result_hash"]) before classification.

Input parameters:

- `baseline` (object, required): The baseline Trace object (typically loaded from a snapshot file).
- `current` (object, required): The current run Trace object to compare against the baseline.
- `ignore_paths` (array): Optional list of path prefixes to drop from both traces before diffing. Each entry matches by exact prefix on the dotted path (e.g. "fingerprint" or "tools[2].result_hash").

### `validate_snapshot` (~83 tokens)

Sanity-check a snapshot object against the agentsnap Trace schema. Verifies required fields (version, tools, fingerprint), tool-entry shape (name + args), and surfaces actionable issues. Returns valid=true on success, otherwise a list of human-readable issues.

Input parameters:

- `snapshot` (object, required): A snapshot object — typically the JSON-decoded contents of a file written by expectSnapshot().
