## 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 2026-11-05.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (ghostkey_session_action).
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 63/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 657 tokens (~65/item across 10 items; 10 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 13/100
  - Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

### How do I install the SCRIPTMASTERLABS — GhostKey MCP server?

SCRIPTMASTERLABS — GhostKey MCP is a hosted endpoint at https://ghostkey-mcp.onrender.com/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.

First indexed and scored.

## MCP tools (10)

### `ghostkey_status` (~35 tokens)

Report GhostKey server status and check whether configured ScriptMasterLabs authorities are reachable. Unknown stays unknown; no health result is fabricated.

### `ghostkey_catalog` (~30 tokens)

List the capabilities actually exposed by this GhostKey MCP server and identify staged families without pretending they are callable.

### `ghostkey_quote` (~54 tokens)

Explain how to obtain authoritative pricing for a GhostKey/SML paid capability. Pricing and settlement destination come from the fresh live HTTP 402 challenge, never a copied wallet or stale fixed price.

Input parameters:

- `capability` (string)

### `ghostkey_policy` (~32 tokens)

Return GhostKey's operating, payment, upstream-rights, browser-session, and trusted-device policy for autonomous agents.

### `ghostkey_device_pairing_create` (~60 tokens)

Create a one-time trusted-device enrollment capability. Requires GhostKey persistent trusted-device storage to be configured. The browser generates its own non-exportable P-256 private key; only the public key is uploaded.

Input parameters:

- `label` (string)

### `ghostkey_device_pairing_status` (~59 tokens)

Resolve a one-time trusted-device pairing after the browser has enrolled. Requires the original pairing ID and pairing code and is available only until that pairing capability expires.

Input parameters:

- `pairing_code` (string, required)
- `pairing_id` (string, required)

### `ghostkey_session_create` (~167 tokens)

PAID tool ($0.10 USDC via x402 v2, Base). Create a short-lived, origin-scoped browser delegation session. Send the x402 PAYMENT-SIGNATURE header on the /mcp request; without payment the call returns the live x402 challenge (HTTP 402, amount 100000 = $0.10 USDC, network eip155:8453). Actions inside a minted session are unmetered. Optionally target a previously enrolled trusted device using its private 256-bit routing capability so its extension can claim the session automatically. The user still handles login/CAPTCHA and any new browser-origin permission themselves.

Input parameters:

- `allowed_origins` (array, required)
- `trusted_device_id` (string)
- `ttl_seconds` (integer)

### `ghostkey_session_status` (~48 tokens)

Check whether a scoped GhostKey browser session is alive and whether its user-controlled browser bridge has a fresh heartbeat.

Input parameters:

- `agent_token` (string, required)
- `session_id` (string, required)

### `ghostkey_session_action` (~132 tokens)

Relay one authorized browser action into the user's already-authenticated browser. Actions: navigate, inspect, click, input, select, read, wait. Password/hidden fields and off-allowlist navigation are denied. API and bridge documentation: https://ghostkey-mcp.onrender.com/session-bridge/README.txt.

Input parameters:

- `action` (string, required)
- `agent_token` (string, required)
- `attribute` (string)
- `selector` (string)
- `session_id` (string, required)
- `text` (string)
- `timeout_ms` (integer)
- `url` (string)

### `ghostkey_session_revoke` (~40 tokens)

Immediately revoke a GhostKey browser delegation session and cancel queued work.

Input parameters:

- `agent_token` (string, required)
- `session_id` (string, required)
