## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `KERNEL_MCP_BROWSER_CURL` | Browser curl | Send an HTTP request through an existing Kernel browser session's Chrome network stack. Use when the request needs that browser session's cookies, proxy, network context, or origin behavior; do not use for general documentation lookup or web search. |
| `KERNEL_MCP_COMPUTER_ACTION` | Computer action | Execute computer actions on a browser session. Pass a single action for simple operations (e.g. one click or one screenshot), or pass multiple actions to batch them into a single request for lower latency (e.g. click, type, press_key in one call). Use sleep actions between steps when the page needs time to react (e.g. after a click that triggers navigation or animation). IMPORTANT: Always include a screenshot as the last action so you can see the result of your actions. Action types: click_mouse, move_mouse, type_text, press_key, scroll, drag_mouse, set_cursor, sleep, write_clipboard, read_clipboard, screenshot, get_mouse_position. screenshot, read_clipboard, and get_mouse_position return data, so they must be the last action if included. |
| `KERNEL_MCP_EXEC_COMMAND` | Exec command | Execute a command synchronously inside a browser VM. Returns stdout, stderr, and exit code. The command field is the executable; use args for its arguments. Common uses: read files (command: "cat", args: ["/var/log/supervisord.log"]), list dirs (command: "ls", args: ["/var/log"]), check DNS (command: "cat", args: ["/etc/resolv.conf"]), test connectivity (command: "curl", args: ["-I", "https://example.com"]). |
| `KERNEL_MCP_EXECUTE_PLAYWRIGHT_CODE` | Execute playwright code | Execute Playwright/TypeScript automation code against an existing Kernel browser session. Does not create or delete browsers -- use manage_browsers to manage session lifecycle. |
| `KERNEL_MCP_GET_CONNECTION_CONTEXT` | Get connection context | Inspect the authenticated Kernel connection before a project-scoped operation. connection_scope.kind=organization may omit project for organization-wide reads and default-project creates, or pass a project name or ID to select a project. connection_scope.kind=project is fixed to connection_scope.project_id; omit project or pass that project. |
| `KERNEL_MCP_GET_MORE_TOOLS` | Get more tools | Check for additional tools whenever your task might benefit from specialized capabilities - even if existing tools could work as a fallback. |
| `KERNEL_MCP_MANAGE_API_KEYS` | Manage api keys | Manage Kernel API keys. Use "create" to create an org-wide or project-scoped key, "list" to discover masked keys, "get" to retrieve one masked key, "update" to rename a key, or "delete" to revoke a key. Created keys include the plaintext key once. |
| `KERNEL_MCP_MANAGE_APPS` | Manage apps | Manage Kernel apps when an agent needs to discover deployed app actions, invoke an app, or inspect deployment/invocation state. Use "list_apps" before invoking an unknown app. "invoke" starts an action asynchronously and returns an invocation_id immediately. Use "list_invocation_browsers" with that ID to discover browser sessions created by the invocation, and use "get_invocation" after a short delay to inspect its state. Do not poll indefinitely; if the invocation is still running, report its ID. Use get/list actions to inspect results and "delete_deployment" to remove a deployment. |
| `KERNEL_MCP_MANAGE_AUTH_CONNECTIONS` | Manage auth connections | Manage reusable authenticated profiles for third-party websites. Before a browser task that needs a user account, call "list" with the exact domain_filter and inspect every page. If one relevant connection is AUTHENTICATED, create the browser with its profile_name. If multiple relevant accounts exist, ask the user which one to use. If authentication is needed and open_auth_login is available, prefer that secure App so credentials and MFA never enter chat: a direct user request to log in is already consent; if login is only discovered incidentally, ask first. For a new App login, choose a concise stable profile name derived from the service unless the user specified one. The programmatic actions remain available for every client: "create" a connection, "login" to start a hosted flow, "submit" fields/MFA/SSO, "get" status, "delete", or "wait" for completion. After authentication, resume the original task with manage_browsers using the verified profile_name. |
| `KERNEL_MCP_MANAGE_BROWSER_POOLS` | Manage browser pools | Manage pre-warmed browser pools when an agent needs fast browser acquisition or reusable session capacity. Use "list" for a compact pool inventory, "get" for full details, "acquire" before controlling a pooled browser, and "release" when the browser should return to the pool. |
| `KERNEL_MCP_MANAGE_BROWSERS` | Manage browsers | Manage browser sessions and their archived telemetry. Use "list" to choose an existing session, "create" before browser control, "update" to change supported session settings, "get" for full details, "get_telemetry" to diagnose active or deleted sessions, and "delete" when finished. get_telemetry compacts events by default; set compact=false with explicit categories and a limit of at most 5 when raw headers, request data, response bodies, or other omitted fields are needed. |
| `KERNEL_MCP_MANAGE_CREDENTIAL_PROVIDERS` | Manage credential providers | Manage external credential providers (e.g. 1Password). "list" returns configured providers, "get" retrieves one by ID, "create" configures a new provider with a service-account token, "update" changes its name/token/priority/enabled/cache_ttl_seconds, "delete" removes it, "list_items" returns available credential items from the provider (e.g. 1Password login items with their paths), and "test" validates the token and lists accessible vaults. |
| `KERNEL_MCP_MANAGE_CREDENTIALS` | Manage credentials | Manage credentials stored in Kernel for managed auth. "list" discovers credentials (optionally filtered by domain), "get" returns a credential's metadata (values are never returned), "totp_code" returns the current 6-digit TOTP for credentials with a configured totp_secret, "create" stores a new credential, "update" changes its name/values/sso_provider/totp_secret (values are merged with existing), and "delete" removes a credential by ID or name. |
| `KERNEL_MCP_MANAGE_EXTENSIONS` | Manage extensions | Manage browser extensions uploaded to Kernel. Use "list" to see all extensions available to the current project or "delete" to remove one by ID or name. |
| `KERNEL_MCP_MANAGE_PROFILES` | Manage profiles | Manage browser profiles when an agent needs persistent cookies, login state, or reusable browser state. Use "setup" for a guided login session, "list" to find a profile, "get" to retrieve one, "rename" to change its name, and "delete" only when a profile should be removed. Do not rename a profile while a browser is using it because that session may no longer save changes back to the profile. |
| `KERNEL_MCP_MANAGE_PROJECTS` | Manage projects | Manage Kernel projects for resource isolation within an organization. Use "create" to create a project, "list" to discover projects, "get" to retrieve one, "update" to rename or archive one, "delete" to remove an empty project, "get_limits" to inspect project caps, or "update_limits" to change project caps. |
| `KERNEL_MCP_MANAGE_PROXIES` | Manage proxies | Manage proxy configurations for routing browser traffic. Use "create" to add a proxy, "list" to see all proxies, "get" to retrieve one, "rename" to change its name, "check" to test connectivity (optionally against a target URL), or "delete" to remove one. Proxy quality for bot detection avoidance, best to worst: mobile > residential > ISP > datacenter. |
| `KERNEL_MCP_MANAGE_REPLAYS` | Manage replays | Manage video replay recordings for a browser session. Use "start" to begin recording a session (returns a replay_id and a viewable URL), "stop" to end a recording and persist the video, or "list" to see all replays for a session with their view URLs. Recording is session-scoped: start once, run your automation, then stop -- rather than recording each action separately. Requires a paid Kernel plan; not available on the free tier. |
| `KERNEL_MCP_SEARCH_DOCS` | Search docs | Search Kernel platform documentation for guides, tutorials, and API references. Use when you need to understand how Kernel features work or troubleshoot issues. |
| `KERNEL_MCP_SUBMIT_FEEDBACK` | Submit feedback | send feedback about anything KERNEL to the KERNEL team. set `feedback_type` to route it: `product` for any KERNEL product or feature, `mcp` for this mcp server, `docs` for KERNEL documentation, or `other`. all sentiments are welcome through `sentiment`: praise and feature requests are useful, not just problems. use this for confusing or broken experiences, papercuts, missing capabilities, unhelpful errors, feature requests, and things that worked especially well. keep `summary` to one sentence and make the detail fields concise and actionable, quoting the product surface, tool name, parameter, or error text when possible. include a concrete `suggested_improvement` when one is clear. never include credentials, tokens, api keys, urls, browser or page content, customer or account names, or personal data. the user can also ask to send feedback directly. submitting feedback is a side report to KERNEL, not a reason to stop: continue and finish the user's task with the other available tools. |
