If you ask the agent for console and network information from the browser opened in the cursor, it responds, “cursor-ide-browser is the only MCP that works with the built-in Cursor browser. It has browser_console_messages and browser_network_requests, but they return a response in an unprocessable format (Unsupported content type “metadata”). This appears to be a bug or implementation limitation.”
Steps to Reproduce
open a browser and ask for access to the console and network
Hey, thanks for the report. It looks like this is a bug in how browser_console_messages and browser_network_requests return their responses. The “Unsupported content type metadata” error means the agent can’t parse the data those tools are sending.
A couple things to check while we look into it:
Do other browser tools work correctly (navigate, click, screenshot)? Or is your whole browser MCP broken?
Go to Settings > Tools & MCP > Browser Automation. Turn the toggle off, wait 10 seconds, then turn it back on. Fully restart Cursor (not just Reload Window), then try again in a new chat.
If it still doesn’t work, please share the Request ID from the failed chat (three dots in the top right of the chat > Copy Request ID) so the team can investigate what’s happening on the server side.
Calling browser_network_requests for this tab returns the error “Unsupported content type ‘metadata’.” This may be a limitation or a bug in the current implementation of the MCP tool.
