{"answer":"Recommended action: For Playwright MCP start the server with --ignore-https-errors (or env PLAYWRIGHT_MCP_IGNORE_HTTPS_ERRORS) or put ignoreHTTPSErrors in browser.contextOptions; in library code pass ignoreHTTPSErrors: true to browser.newContext()/launchPersistentContext() with the exact spelling. Prefer installing the internal CA into the environment when possible.\n\nOption: Use the MCP flag or contextOptions [evidence: official_recommended_action]\nApplies when: Playwright MCP servers used by coding agents\nSteps:\n1. Add \"--ignore-https-errors\" to the MCP server args, or set browser.contextOptions.ignoreHTTPSErrors=true in the config file\n2.
