## 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 2026-09-21.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs setuptools.build_meta at install time, a recognised native-build step with no shell scripting around it.
  - 1 of 32 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 35/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - License check failed: no license is declared.
  - Actively maintained (last published 1 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 60/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 468 tokens (~78/item across 6 items; 6 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

**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.

## MCP tools (6)

### `loopgrid.record_decision` (~137 tokens)

Capture a consequential AI/agent decision in LoopGrid. Optionally record model output and evaluate an existing LoopGrid policy. This records evidence only and does not execute the proposed action.

Input parameters:

- `agent_id` (string)
- `agent_version`
- `authority`
- `context`
- `decision_type` (string, required)
- `idempotency_key`
- `input_data`
- `metadata`
- `model`
- `model_output`
- `policy_id`
- `privacy_mode`
- `proposed_action` (object, required)
- `service_name` (string)

### `loopgrid.record_review` (~66 tokens)

Record a human approve/reject review in LoopGrid. Disabled by default. The operator must explicitly enable it and configure reviewer identity; the MCP host should require human confirmation.

Input parameters:

- `action` (string, required)
- `decision_id` (string, required)
- `reason` (string)

### `loopgrid.record_action` (~80 tokens)

Record evidence that an external tool/action executed. This does NOT call Stripe, Salesforce, ServiceNow, or any other business system; it only records execution evidence supplied by the integration.

Input parameters:

- `actor_id` (string)
- `decision_id` (string, required)
- `details`
- `external_reference`
- `tool` (string, required)

### `loopgrid.record_outcome` (~81 tokens)

Record an observed downstream outcome for a decision after execution evidence exists. The integration is responsible for obtaining the outcome from the real downstream system.

Input parameters:

- `actor_id` (string)
- `decision_id` (string, required)
- `details`
- `external_reference`
- `status` (string, required)
- `verified_against` (string, required)

### `loopgrid.get_evidence` (~54 tokens)

Download a portable LoopGrid evidence ZIP for a decision to the configured local evidence directory. Raw disclosure payloads are excluded by default.

Input parameters:

- `decision_id` (string, required)
- `include_payloads` (boolean)

### `loopgrid.verify_evidence` (~50 tokens)

Ask the connected LoopGrid service to verify the decision's signed workspace chain. For independent offline verification of an exported ZIP, use the standalone LoopGrid verifier.

Input parameters:

- `decision_id` (string, required)

## Common questions

### What is the LoopGrid MCP server?

LoopGrid MCP is listed in the public MCP registry as io.github.loopgridio/loopgrid-mcp. MCP bridge for tamper-evident evidence around consequential AI and agent decisions. This page covers its PyPI package (loopgrid-mcp).

### Is the LoopGrid MCP server safe to use?

LoopGrid MCP scores 63 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 21 September 2026. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the LoopGrid MCP server expose?

LoopGrid MCP exposes 6 tools: loopgrid.record_decision, loopgrid.record_review, loopgrid.record_action, loopgrid.record_outcome, loopgrid.get_evidence, loopgrid.verify_evidence. Their descriptions and schemas cost roughly 468 tokens of context every time the server is loaded.

### Is the LoopGrid MCP server still maintained?

LoopGrid MCP is still listed as active in the MCP registry. We last reached this channel on 21 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
