What is MCP specification revision 2026-07-28?

MCP 2026-07-28 is the current stable revision of the Model Context Protocol specification, released 2026-07-28.

Which servers and clients support MCP 2026-07-28?

524 entities have a verified support record against 2026-07-28: 48 supported, 0 partial, 476 not supported. Each record links its evidence URL and check date.

The largest revision since the protocol launched: the core becomes stateless (the initialize handshake and protocol-level sessions are removed), server/discover is introduced, Multi Round-Trip Requests replace server-initiated requests, routing headers and cacheable list results land, and a formal extensions framework and 12-month deprecation policy are adopted.

What changed in MCP 2026-07-28?

  • Stateless protocol core: initialize/initialized handshake and the Mcp-Session-Id header removed; every request carries protocol version, client identity, and capabilities in _meta
  • New server/discover RPC (servers MUST implement it) advertises supported protocol versions, capabilities, and identity
  • Multi Round-Trip Requests (MRTR) replace server-initiated elicitation/create, sampling/createMessage, and roots/list
  • Mcp-Method and Mcp-Name headers required on Streamable HTTP requests for header-based routing
  • Cacheable list results: ttlMs and cacheScope required on tools/list, prompts/list, resources/list, resources/read
  • subscriptions/listen replaces the HTTP GET stream and resources/subscribe
  • Tasks move to the io.modelcontextprotocol/tasks extension; extensions framework formalized (Tasks, MCP Apps, Enterprise Managed Authorization)
  • Authorization hardening: RFC 9207 issuer validation, credentials bound to issuer, Dynamic Client Registration deprecated in favor of Client ID Metadata Documents
  • Roots, Sampling, Logging, and the legacy HTTP+SSE transport deprecated under a formal feature lifecycle with a twelve-month minimum removal window

MCP 2026-07-28 is the current stable revision of the Model Context Protocol specification and its largest revision to date. The protocol core becomes stateless: the initialize handshake and protocol-level sessions are retired, every request is self-contained, and any request can land on any server instance behind a plain load balancer. Servers must implement the new server/discover RPC; clients may call it for up-front capability discovery but are not required to.

Server-initiated requests are redesigned as Multi Round-Trip Requests: a tool that needs mid-call input returns an input_required result and the client retries the original call with the answers attached. Streamable HTTP requests must carry the Mcp-Method and Mcp-Name headers, list results carry cache hints, and change notifications consolidate into a single subscriptions/listen stream.

Roots, Sampling, Logging, and the legacy HTTP+SSE transport are deprecated under the newly adopted feature lifecycle policy, which guarantees a twelve-month minimum window before removal. Tasks graduate into the formal extensions framework alongside MCP Apps and Enterprise Managed Authorization. The four Tier 1 SDKs (TypeScript, Python, Go, C#) shipped support on release day.
