Available components
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. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- 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. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability82
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 896 tokens (~89/item across 10 items; 9 tools + 1 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage73
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 18% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
- Supports UI / widget rendering.Pass
How do I install the GHOSBC Safety Gate MCP server?
GHOSBC Safety Gate is a hosted endpoint at https://cibcxqrqiqvzpardbdrw.supabase.co/functions/v1/ghosbc-safety-gate-mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
audit_a2a_agent_card Audit A2A Agent Card trust ~108
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.
| Name | Type | Req | Description |
|---|---|---|---|
| card_url | string | yes | Public HTTPS A2A Agent Card URL, normally /.well-known/agent-card.json. |
No output schema declared.
No examples provided.
audit_mcp_dependency Audit MCP dependency ~85
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.
| Name | Type | Req | Description |
|---|---|---|---|
| endpoint_url | string | yes | Public HTTPS MCP endpoint. |
No output schema declared.
No examples provided.
audit_shopify_agentic_storefront Audit Shopify agentic storefront ~115
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.
| Name | Type | Req | Description |
|---|---|---|---|
| store | string | yes | Public Shopify store domain or HTTPS URL, for example store.myshopify.com. |
No output schema declared.
No examples provided.
buy_policy_checks ~50
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
sanitize_agent_payload ~57
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.
| Name | Type | Req | Description |
|---|---|---|---|
| payload | – | yes | – |
No output schema declared.
No examples provided.
screen_agent_request ~83
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.
| Name | Type | Req | Description |
|---|---|---|---|
| capabilities | array | – | – |
| mode | string | – | – |
| text | string | yes | – |
No output schema declared.
No examples provided.
screen_consequential_action ~125
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.
| Name | Type | Req | Description |
|---|---|---|---|
| action | string | yes | – |
| amount | number | – | – |
| constraints | object | – | – |
| currency | string | – | – |
| target | string | – | – |
No output schema declared.
No examples provided.
screen_mcp_tool_definition ~96
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.
| Name | Type | Req | Description |
|---|---|---|---|
| annotations | object|null | – | – |
| description | string | – | – |
| inputSchema | object|null | – | – |
| name | string | yes | – |
No output schema declared.
No examples provided.
validate_agent_response ~51
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.
| Name | Type | Req | Description |
|---|---|---|---|
| response | – | yes | – |
No output schema declared.
No examples provided.
