New internal helper functions now parse an MCP server's endpoint before it's reported in logs or telemetry, and redact anything sensitive: they mask template placeholders, strip credentials and file paths from URLs down to just the origin or host, and replace sensitive substrings with `x` characters or `${...}` placeholders.\n\n**Why**\n\nThis prevents credentials, file paths, or other sensitive details embedded in an MCP server's connection string from leaking into logs or telemetry data.\n\n- Area: MCP\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 1\/5"}
