Get paired, stay connected, recover safely.

Requirements

• Android 8 or newer.
• Cursor desktop with the FireCursor extension and at least one configured runtime: Cursor Agent, Codex through the local bridge with managed ChatGPT sign-in, or Claude through eligible-plan Channels or the separately billed API fallback.
• A computer that remains awake and online while you control local agents. Cursor Cloud Agents can continue while it is off.
• Install-from-unknown-apps permission for the direct preview APK.

Install and pair

• Install the Cursor extension from the downloaded .vsix.
• In Cursor's Extensions view, open More Actions, choose Install from VSIX, and select firecursor.vsix.
• Run FireCursor: Start Remote Control in Cursor.
• In the pairing panel's Agent runtimes section, verify or set up Cursor, Codex, and Claude. Only one ready runtime is required to begin.
• Install and open the Android preview APK.
• Create an account on firecursor.com, verify your email, set a password, and sign in to Android with the same email and password. Referral attribution is captured automatically when you join through a valid invite link.
• When Android asks, allow direct app installs only for the browser used to download the APK, then return to the download and tap Install.
• Scan the private QR code and keep it out of screenshots or shared logs.

Reconnect behavior

FireCursor stores the pairing token and both tunnel and same-network endpoints. When the phone can reach the computer over LAN, it can learn a refreshed tunnel endpoint automatically. If the tunnel rotates while the phone is remote and the LAN path is unavailable, pairing again may still be required.

Before contacting support

• Open the pairing panel and confirm that the provider you selected reports Ready. Use its Set up action if it does not.
• For Claude, confirm that the account includes Claude Code (Pro, Max, or an eligible organization plan). Claude Free cannot authenticate Claude Code; an API key uses separate Anthropic billing.
• Restart remote control in Cursor and check the connection status.
• Verify the computer is online and not asleep.
• Include Android and extension versions plus a redacted error message.
• Never send a pairing token, QR code, API key, credential, or private source file.
