Bumps mcp[client,server] from 1.21.0 to 1.26.0.

Release notes

Sourced from mcp[client,server]'s releases.

v1.26.0

What's Changed

Full Changelog: modelcontextprotocol/python-sdk@v1.25.0...v1.26.0

v1.25.0

Branching Update

Starting with this release, the repository has adopted a new branching strategy for v2 development:

  • main — v2 development (breaking changes)
  • v1.x — v1 maintenance (security and critical bug fixes only, with very rare feature additions ported from main)

Users who need to stay on v1.x should pin to mcp>=1.25,<2.

The current plan is to work through v2 and have it released some time in Q1. This also relies on the next upcoming spec release which will heavily change how the transport layer works, which in turn will guide a lot of how we architect v2.
