TL;DR: MCP’s 2026 release candidate replaces sticky sessions, protocol-level session state, and ad hoc governance with stateless routing, explicit handles, and formal lifecycle rules, according to Obot. The shift makes MCP easier to deploy in enterprise environments, but it also pushes authorization, auditability, and configuration control into surrounding identity and gateway layers.
NHIMG editorial — based on content published by Obot: MCP 2026 release candidate and the roadmap toward enterprise readiness
By the numbers:
- The release candidate locked on May 21, giving SDK maintainers and client implementers a ten-week window to validate the changes before final publication.
Questions worth separating out
Q: How should security teams govern MCP in enterprise environments?
A: Treat MCP as an identity and authorization problem first.
Q: What breaks when MCP clients and servers still assume sticky sessions?
A: Sticky-session assumptions break routing, scaling, and identity validation when the protocol no longer maintains connection-bound state.
Q: When should organisations prioritise gateway controls over protocol features?
A: They should do it as soon as MCP is used beyond isolated experiments.
Practitioner guidance
- Map MCP trust boundaries to identity controls Identify where authorization, audit logging, and policy enforcement actually occur in your MCP deployment.
- Validate request-scoped state handling Test how handles, metadata, and downstream tool arguments behave across retries, load balancers, and failover events.
- Inventory deprecated MCP capabilities now Build a migration list for Roots, Sampling, Logging, and any other capability moving through the Active to Deprecated to Removed lifecycle.

MCP’s shift to stateless transport exposes the real enterprise control boundary. Once protocol sessions disappear, sticky routing and shared session stores stop being the security anchor. That means the control plane moves to the surrounding identity, gateway, and authorization layers, where NHI governance has to be explicit rather than implied. The implication is that enterprises should stop treating protocol state as a trust mechanism and start governing the boundary that actually enforces access.
A few things that frame the scale:
- 80% of organisations report their AI agents have already performed actions beyond their intended scope, including accessing unauthorised systems (39%), inappropriately sharing sensitive data (31%), and revealing access credentials (23%), according to AI Agents: The New Attack Surface report.
- Only 44% of companies have implemented any policies to govern AI agents, leaving the majority without formal runtime controls for non-human decision makers.
A question worth separating out:
Q: Who is accountable for MCP lifecycle governance and deprecation tracking?
A: The accountable team is the platform or identity owner that operates the MCP boundary, not the protocol working group. Governance has to cover deprecated features, replacement paths, and cutover planning so server teams do not discover removals only when client behaviour starts failing.
