v8.0.0

8.0.0 (2025-12-18)

Full Changelog: v7.0.0...v8.0.0

⚠ BREAKING CHANGES

• mcp: remove deprecated tool schemes
• mcp: Migration: To migrate, simply modify the command used to invoke the MCP server. Currently, the only supported tool scheme is code mode. Now, starting the server with just node /path/to/mcp/server or npx package-name will invoke code tools: changing your command to one of these is likely all you will need to do.

Bug Fixes

• mcp: pass base url to code tool (631bb5c)

• mcp: remove deprecated tool schemes (9b1ff85)
