File-based server definitions are resolved through a containment check rather than a plain path join, so a plugin cannot point outside its own directory.\n\n**Details**\n\n- The mode is an option at the call site and is off by default.\n- MCPB bundle sources are refused in listing mode, with an explanation that they require the pre-approval download.\n- The skip warning now says \"directory-loaded plugin\" instead of \"project-scope @skills-dir plugin\".\n\n**Evidence**\n\n`Skipping MCPB source`\n\n- Area: MCP\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 3\/5"}
