Which MCP Server Should You Choose?
Choose Kernel MCP Server when:
You need dedicated capabilities in the Developer Tools domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Create, update, list, get, and delete browser sessions, and read archived telemetry for active or deleted sessions. Supports headless/stealth modes, profiles, proxies, viewports, extensions, names and tags, and SSH tunneling. The browser tools (`manage_browsers`, `computer_action`, `execute_playwri…
manage_profiles
Setup (with guided live browser session), search/list with pagination, get, and delete browser profiles for persisting cookies and logins.
manage_projects
Create, list, get, update, and delete organization projects. Inspect and update per-project resource limits.
manage_api_keys
Create, list, get, update, and delete org-wide or project-scoped API keys. Create returns the plaintext key once.
manage_browser_pools
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Kernel MCP Server is categorized under Developer Tools and uses a local stdio subprocess. In contrast, Kiaaccess MCP belongs to Developer Tools using local stdio subprocess. Select Kernel MCP Server when you need capabilities focused on developer tools and Kiaaccess MCP when you require tools for developer tools.
Start, stop, and list MP4 video replay recordings for a browser session. Session-scoped: start once, run your automation, then stop. Requires a paid Kernel plan.
manage_extensions
List and delete uploaded browser extensions.
manage_apps
List/search apps, invoke actions, get/list/delete deployments, and get invocation results.
manage_auth_connections
Create, list, get, update, delete, login, submit, inspect timelines, and wait for managed-auth connections in every client. Supports health-check and automatic re-auth settings, managed-auth browser configuration, and canonical interaction-bound field/choice submissions. Use domain-filtered `list`…
manage_credentials
Create, list, get, update, and delete stored credentials; fetch a current TOTP code for credentials with a configured totp_secret.
manage_credential_providers
Create, list, get, update, and delete external credential providers (e.g. 1Password); list available items and test the provider connection.

Kiaaccess MCP Tools (18)
kia_session_status
Configured? Bootstrapped? Which write mode? No network call, no secrets — the email is masked and the device id truncated.
kia_start_login
Step 1 of the MFA bootstrap. Confirm-gated, because a rejection has a permanent cost.
kia_send_otp
Step 2 — delivers the passcode by `SMS` or `EMAIL`.
kia_verify_otp
Step 3 — exchanges the passcode for a stored session. Returns no secret.
kia_forget_session
Discards the stored token so the bootstrap can be re-run. Local only; confirm-gated.
kia_export_refresh_token
Returns the `rmtoken` **in plaintext** — a full MFA bypass. Exists only to move a locally-bootstrapped session into a deployment that cannot run the bootstrap itself, via `KIA_RMTOKEN`. Confirm-gated.
kia_list_vehicles
Every enrolled vehicle with its `vehicleKey`, nickname, model, mileage. VINs are masked to the last 6 characters.
kia_vehicle_status
Cached status: door lock, ignition (`ign3` — on an EV `engine` stays false), the nested `climate` block, and more with `include_raw`. Fast, but only as fresh as the last upload.
kia_refresh_status
Wakes the telematics unit for a fresh reading. Slower, draws a little power, and returns no data itself — read `kia_vehicle_status` afterwards.
kia_vehicle_location
Last reported position plus a map link. Not a live GPS fix.
kia_charge_targets
Target state of charge per plug type.
kia_start_climate
Preconditioning. Temperature is best-effort: the car may report its own last-set target instead of the one requested.
