Versions	5.0, 6.0
Edition

https://modelcontextprotocol.io/docs/ is now versioned

• 2 introduction links might address topics that are version dependents.
• The MCP inspector link should target the latest version so let's ignore its redirection.

Side note: https://modelcontextprotocol.io/specification/2026-07-28 is released but not covered by our MCP Servers yet.

• Text has been checked with vale
• Description metadata is up to date
