Not able to perform Put and Patch call while performing API testing using MCP Server.
Steps to Reproduce - 1- Provide prompt to perform Update API Call (More details are in this link - https://fakerestapi.azurewebsites.net/index.html ) 2 - Provide valid body with put call - { "id": 1, "title": "string", "dueDate": "2025-08-18T20:48:58.627Z", "completed": true } 3- Send the Prompt in Copilot or Claude or any other AI Assistant.
Issue - In Postman call is successful and it is giving response but when we are using MCP Server it is not able to perform API Put and Patch API calls. , I have tried same with other website API calls also.
Adding Claude / Copilot response - The PUT request returned a 415 Unsupported Media Type error. This suggests the API requires specific headers that aren't being set by the playwright_put function.
Unfortunately, the current Playwright EA MCP Server tools don't provide a way to send a PUT request with custom headers like the accept and Content-Type headers specified in your curl command. The playwright_put function only accepts a URL and body value, but doesn't have a headers parameter like the playwright_post function does.
