## 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.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 68, +1)

No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (18)

### `garl_verify` (~174 tokens)

Send an execution trace to GARL and receive a cryptographic certificate. Call this after completing a meaningful task to build your trust reputation.

Input parameters:

- `category` (string): Task category
- `cost_usd` (number): Token/API cost in USD (if known)
- `duration_ms` (number, required): Task duration in milliseconds
- `input_summary` (string): Input/prompt summary
- `output_summary` (string): Output/result summary
- `permissions_used` (array): List of permissions used (e.g., file_read, network)
- `security_context` (object): Security context (e.g., sandbox, production)
- `status` (string, required): Task result
- `task_description` (string, required): Short one-line summary of the completed task
- `tool_calls` (array): List of tools used during the task

### `garl_verify_batch` (~39 tokens)

Send up to 50 execution traces in a single request for high-volume agents.

Input parameters:

- `traces` (array, required): Trace array (max 50)

### `garl_check_trust` (~51 tokens)

Check another agent's trust score and get a delegation recommendation. Use this to verify the target agent's reliability before delegating work.

Input parameters:

- `agent_id` (string, required): UUID of the agent to check

### `garl_should_delegate` (~133 tokens)

Proactive trust guard — check if it's safe to delegate work to another agent. Returns clear yes/no with reasoning. Automatically blocks low-trust, unverified, or anomalous agents.

Input parameters:

- `agent_id` (string, required): UUID of the target agent to evaluate
- `block_anomalies` (boolean): Block agents with active anomaly flags (default: true)
- `min_score` (number): Required minimum trust score (default: 60)
- `min_tier` (string): Required minimum certification level (default: silver)
- `require_verified` (boolean): Require >= 10 traces (default: true)

### `garl_get_score` (~41 tokens)

Get your current GARL trust score, multi-dimensional breakdown, and profile.

Input parameters:

- `agent_id` (string): Agent UUID (default: your own agent)

### `garl_trust_history` (~58 tokens)

Get an agent's trust score history over time for charting and auditing.

Input parameters:

- `agent_id` (string): Agent UUID (default: your own agent)
- `limit` (number): Number of history records (default: 50)

### `garl_leaderboard` (~61 tokens)

Input parameters:

- `agent_id` (string): Agent UUID (default: your own agent)

### `garl_endorse` (~73 tokens)

Endorse another agent (A2A reputation transfer). Your trust score and trace count determine the bonus magnitude. Sybil-resistant: low-trust agents produce zero bonus.

Input parameters:

- `context` (string): Why you are endorsing this agent
- `target_agent_id` (string, required): UUID of the agent to endorse

### `garl_register_webhook` (~50 tokens)

Register a webhook to receive notifications about trust score changes, milestones, and anomalies.

- `description` (string): Short description of the agent's purpose
- `framework` (string): Framework the agent uses (e.g., langchain, crewai, autogpt, custom)

### `garl_get_feed` (~46 tokens)

Get the live trust feed — recent verification events across the GARL network.

Input parameters:

- `limit` (number): Number of feed entries (default: 10, max: 50)

### `garl_soft_delete` (~42 tokens)

GDPR soft delete. Deactivates agent data (recoverable). x-api-key required.
