MCP 2026-07-28 RC: Stateless Transport
The news. On May 22, 2026, the MCP project landed PR #2750 — the blog announcement for the 2026-07-28 specification release candidate. The post leads with the stateless transport rework as the headline change, with a before/after HTTP example showing a self-contained tools/call request. Extensions, MCP Apps, and Tasks follow as the new capability story; the authorization changes are summarized by the failure modes they fix rather than enumerated SEP-by-SEP. All twenty-two scoped SEPs are linked from the announcement.

I Wired 8 MCP Servers Into One Claude Agent. 3 Pairs Quietly Fought Over the Same Tool Name.
There is a pending proposal (#287) to add namespace prefixes server-side, dated around early 2026, but as of writing it has not landed and the client implementations have not picked it up. So this is an "until further notice" problem.

MCP SEP-2468: RFC 9207 Iss Parameter for OAuth Mix-Up Defense
The news. On May 17, 2026, MCP SEP-2468 was merged into the Model Context Protocol specification — proposed March 25, accepted May 5. The change recommends that authorization servers advertise iss support in their metadata and include the parameter in their authorization responses, and requires clients to validate it against the recorded issuer using simple string comparison per RFC 3986 §6.2.1. The motivation, taken directly from RFC 9207, is to close the long-standing OAuth mix-up attack in clients that trust multiple identity providers.

Claude's Paid Subscribers Are Skyrocketing
Semrush data fills in the picture. Claude.ai hit 220 million monthly visits in January 2026, then jumped 30.9% to 288 million in February. Meanwhile, the Model Context Protocol SDK hit 97 million monthly downloads in March, up from 2 million at launch in November 2025. That's 4,750% growth in 16 months. The developer ecosystem is building momentum that feeds back into consumer adoption.

Production-Ready MCP: Why Security Standards Matter for AI Tool Infrastructure
The Solution: User-specific authorization flows. The MCP server obtains tokens scoped to individual users, inheriting their permissions from the downstream systems. This is what our PR #475 addresses—enabling secure token exchange without exposing credentials to clients or LLMs.

Show HN: Active MCP: A Rails engine that provides MCP capabilities to Rails app
No. Any file that runs MCP Server is fine anywhere. I am intending a workspace separate from the rails app. The MCP server should be run in a separate process from the rails app. At least until the streamable http transport is ready.

I explain the Model Context Protocol or MCP used to interact with LLMs
Another aspect worth noting is that, to date, the protocol requires a persistent connection between client and server, so this can be a drawback for auto-scalable architectures that adapt to demand, as well as moving in the opposite direction in a world that is striving to become stateless.
