| Client coverage | ||
| Client coverage details | Not documented | Claude Code✓ Local stdio Claude Desktop✓ Local stdio Codex✓ Local stdio VS Code✓ Local stdio Cursor✓ Local stdio OpenCode✓ Local stdio |
| Client coverage note | Local stdio runs on your computer. Streamable HTTP connects to a remotely hosted MCP server. | |
| Access and data | ||
| Authentication | Mux OAuth for clients that support it; otherwise a Mux access token created in the Mux Dashboard. | The server itself does not require a service account for local stdio use, but websites opened in the controlled browser may use cookies or other authenticated browser state. |
| Cost | The MCP server does not document a separate MCP fee. Mux product/API usage can incur normal Mux plan and usage charges; Mux pricing includes usage credits/free allowances and usage-based charges beyond them. | The first-party open-source package lists no MCP server usage fee. Normal internet, hosted-client, proxy, or third-party website costs can still apply. |
| Permissions | The MCP server acts within the Mux environment and access-token permissions you authorize. Mux explicitly recommends a token with Read permissions when you want to prevent changes. | The exposed tools can navigate pages, interact with elements, enter text, upload files, inspect network activity, and optionally use additional browser capabilities. |
| Data handling | Not documented in the reviewed sources. The reviewed Mux MCP documentation does not make a specific MCP request-retention or training claim. | Page text, accessibility snapshots, console output, network details, uploaded paths, and browser state may be returned to the connected MCP client. Isolated mode keeps the temporary profile in memory; persistent mode stores browser state on disk. |
| Limitations | ||
| Tradeoffs |
|
|
| Risk context | The code-mode execute tool can perform SDK operations allowed by the credential, including state-changing operations. Mux states that destructive operations are not specially blocked by the MCP server. | Playwright MCP is not a security boundary. Secret replacement or masking is a convenience feature, not a security boundary. Prefer an isolated browser profile, non-sensitive test accounts, narrow destinations, minimal optional permissions, and client-side approval controls. |
