## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, 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 2026-09-20.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 9 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 82/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 896 tokens (~89/item across 10 items; 9 tools + 1 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 73/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 18% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 11 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).
  - Supports UI / widget rendering.

## MCP tools (9)

### `audit_a2a_agent_card` (~108 tokens)

Audit A2A Agent Card trust

Use before depending on an unfamiliar A2A agent. Reads only the public Agent Card and optional public registry metadata, checks declared bindings/protocol versions, skill descriptions, security declarations and registry task-verification evidence, then returns a trust/readiness score plus shareable badge metadata. It does not send a task to or execute any skill on the target agent.

Input parameters:

- `card_url` (string, required): Public HTTPS A2A Agent Card URL, normally /.well-known/agent-card.json.

### `audit_shopify_agentic_storefront` (~115 tokens)

Audit Shopify agentic storefront

Use to inspect a public Shopify store's AI-shopping surface before an autonomous agent trusts it. Reads only public /.well-known/ucp, /agents.md and /api/ucp/mcp metadata, runs initialize/tools/list, screens exposed tool definitions, and returns a readiness/risk packet. It never creates or mutates carts, checkouts, orders, payments, credentials, or store data.

Input parameters:

- `store` (string, required): Public Shopify store domain or HTTPS URL, for example store.myshopify.com.

### `audit_mcp_dependency` (~85 tokens)

Audit MCP dependency

Use for a public remote MCP server that an autonomous agent depends on. Remembers the tools/list baseline, returns only added/removed/modified tools, screens new or changed tool definitions, and produces one aggregate ALLOW/REVIEW/BLOCK decision. It does not inspect server source code or authenticated/private MCP endpoints.

Input parameters:

- `endpoint_url` (string, required): Public HTTPS MCP endpoint.

### `screen_agent_request` (~83 tokens)

Use before an agent follows untrusted instructions or requests capabilities. Returns ALLOW, REVIEW, or BLOCK plus an audit digest. Best for prompt/policy routing; use screen_consequential_action for a concrete purchase, write, deployment, deletion or other bounded action.

Input parameters:

- `capabilities` (array)
- `mode` (string)
- `text` (string, required)

### `screen_mcp_tool_definition` (~96 tokens)

Use before exposing a third-party MCP tool to an autonomous agent, or after a tool definition changed. Screens name, description, schema and annotations for injection-like language, credential/private-context surfaces, side-effect risk and weak contracts. Advisory metadata gate, not source-code verification.

Input parameters:

- `annotations` (object|null)
- `description` (string)
- `inputSchema` (object|null)
- `name` (string, required)

### `screen_consequential_action` (~125 tokens)

Use immediately before a consequential agent action such as purchase, payment, transfer, send, deploy, publish, execute, cart mutation, checkout mutation, or delete. Compares the proposed action with caller-declared allowed actions/targets, amount ceiling, currency and expiry. ALLOW only when explicit bounds fit; REVIEW when bounds are missing; BLOCK when limits are violated. Does not execute the action.

Input parameters:

- `action` (string, required)
- `amount` (number)
- `constraints` (object)
- `currency` (string)
- `target` (string)

### `sanitize_agent_payload` (~57 tokens)

Use before sending context to an external model, tool or agent when the payload may contain credentials or private material. Redacts common secret patterns and flags policy-extraction language. Not a complete DLP/compliance system.

Input parameters:

- `payload` (required)

### `validate_agent_response` (~51 tokens)

Use immediately before an agent delivers a response outside its trust boundary. Flags likely credential leakage or policy-extraction content and returns a sanitized response when review is needed. Not factuality verification.

Input parameters:

- `response` (required)

### `buy_policy_checks` (~50 tokens)

Use only when free usage is exhausted or production volume is needed. Returns Stripe checkout for 10,000 prepaid GHOSBC Safety Gate checks for $19; it does not charge or receive payment credentials.

## Common questions

### What is the GHOSBC Safety Gate MCP server?

GHOSBC Safety Gate is an MCP server listed in the public MCP registry as io.github.MisfitMEdiAhouse/ghosbc-safety-gate. Agent governance with A2A/Shopify/MCP trust audits, action screening, and decision UI. This page covers its hosted endpoint (https://cibcxqrqiqvzpardbdrw.supabase.co/functions/v1/ghosbc-safety-gate-mcp).

### Is the GHOSBC Safety Gate MCP server safe to use?

GHOSBC Safety Gate scores 80 out of 100 on VerifyMCP. 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 GHOSBC Safety Gate MCP server expose?

GHOSBC Safety Gate exposes 9 tools: audit_a2a_agent_card, audit_shopify_agentic_storefront, audit_mcp_dependency, screen_agent_request, screen_mcp_tool_definition, and 4 more. Their descriptions and schemas cost roughly 770 tokens of context every time the server is loaded.

### Does the GHOSBC Safety Gate MCP server require authentication?

No. We connected to GHOSBC Safety Gate without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the GHOSBC Safety Gate MCP server still maintained?

GHOSBC Safety Gate is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
