Cause (Documented platform behavior): The MCP disambiguates which binary is missing and surfaces the expected path so version mismatches are visible.
Fix status: documented_behavior
Limitations:
- Generic Playwright 'Executable doesn't exist' is a separate atlas record; this is the MCP wording and install command
Other error fragments:
- npx @playwright/mcp install-browser
