Sep 15, 2026 · 57 sources

MCP's stateless core lands and connectors must adapt

The 2026-07-28 MCP spec centers a stateless core, and that reshapes how retrieval connectors are deployed, authed, and scaled.

Sep 11, 2026 · 65 sources

Stateless MCP makes agent memory your problem

MCP's move away from long-lived sessions pushes retrieval state into your orchestrator — and flat top-k is the wrong primitive for it.

Sep 10, 2026 · 60 sources

Stateless MCP reshapes how knowledge connectors get built

MCP's move toward stateless servers pushes session and memory state out of your connector layer — here's what that changes in a RAG stack.

Sep 5, 2026 · 58 sources

MCP Went Stateless and Tool Discovery Is Next

July's spec turned MCP servers into ordinary HTTP services; the August roadmap moves the hard problem to tool-catalog retrieval and agent identity.

Sep 4, 2026 · 60 sources

Enterprise-managed MCP auth moves the ACL problem

Anthropic's org-level authorization for Claude's MCP connectors changes who owns permission-aware retrieval — and what your MCP server has to implement.

Sep 3, 2026 · 58 sources

MCP went stateless and your memory layer inherits the job

The 2026-07-28 spec drops session state from the transport, and the new roadmap turns tool discovery into a retrieval problem you own.

Sep 2, 2026 · 65 sources

ByteDance open-sourced a filesystem for agent context

OpenViking swaps flat top-k vector search for directory-walk retrieval, and the argument behind it is stronger than the code.

Aug 13, 2026 · 70 sources

MCP goes stateless and your connectors must follow
