Capabilities

Tools 10

ghostkey_catalog

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

Discovered
ghostkey_device_pairing_create

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.

Discovered
ghostkey_device_pairing_status

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.

Discovered
ghostkey_policy

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

Discovered
ghostkey_quote

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.

Discovered
ghostkey_session_action

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.

Discovered
ghostkey_session_create

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.

Discovered
ghostkey_session_revoke

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

Discovered
ghostkey_session_status

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

Discovered
ghostkey_status

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