I’m trying to run Puppeteer MCP on the N8N, it works normally up to the MCP node with operation List Tools, but on the next MCP node with operation Execute Tool it gives this error. Can anyone help me solve it? I’ve tried a lot of things and it still gives this error.
In this case, I asked it to access google, then the AI Agent node executes the first tool that has the operation list tools, but when it executes the tool that has the operation execute tool, it gives the error.
Failed to execute operation: Operation not permitted, make sure you have the right permissions
