Task: News/Analysis Article on a Major MCP Update

Background

The Tessl editorial team monitors the MCP (Model Context Protocol) ecosystem closely, as it directly affects how Tessl's agent infrastructure fits into the broader developer tooling landscape. A significant update was recently announced that the team wants to cover for the blog.

The editorial lead's brief:

"We want a news and analysis piece, not a press release. Give readers the facts (version, what changed, pricing if any, platform support), then give them your read on what it actually means for developers building agents. Use suggestive language when describing what the MCP team says their update does — we don't want to parrot their marketing. If there's a natural Tessl angle, include it, but don't force it. End with what to watch going forward."

The Update to Cover

Write about the following (invented but realistic) announcement:

Announcement: MCP Server SDK 2.0 released by Anthropic

• Version: 2.0.0, released under Apache 2.0 license
• Key changes:
  • New "streaming context" transport layer that aims to reduce context handoff latency
  • Native support for OAuth 2.1 authentication flows in server-to-server connections
  • Breaking change: the context.push() API is deprecated; replaced by context.stream()
  • Pricing: SDK remains free and open source; hosted relay service introduced at $0.004 per 1,000 context tokens
  • Platform support: Node.js 18+, Python 3.11+, Go 1.22+
• The MCP team's stated goal is to make context delivery more reliable in multi-agent pipelines
• Early adopters in a beta program reported latency improvements in context handoff; specific numbers not independently verified

What to Write

Write a publish-ready news and analysis article for the tessl.io blog covering the MCP Server SDK 2.0 release. The article should:

• Lead with what happened and why it matters
• Cover the specific details: version number, key changes, pricing, platform support
• Analyze what this actually means for developers building agents (the "So what?" section)
• Use appropriately cautious language when describing claimed benefits, since the improvements have not been independently verified
• Optionally include a Tessl angle if it fits naturally
• Close with what developers should watch for as the ecosystem responds

Output Specification

Save the completed article as article.md in the current working directory.

The file must include a metadata block at the top (title, type, primary keyword, meta description, URL slug, internal links, estimated read time) followed by the full article body in markdown.
