A CLI tool that wraps stateful MCP servers and externalizes their session state so they run behind standard round-robin load balancers without sticky routing

Existing MCP servers built on the 2025-11-05 stateful spec rely on in-process session state that breaks under horizontal scaling because round-robin load balancers route requests to the wrong instance. The MCP 2026-07-28 RC removes the stateful handshake at the protocol level, leaving every existing stateful MCP server needing a migration path. This tool wraps any existing MCP server binary, intercepts session lifecycle calls, externalizes session state to Redis or a compatible KV store, and re-exposes the server as a stateless-compatible endpoint that runs behind any vanilla AWS ALB or Cloudflare load balancer with zero sticky-session config.

Gap Assessment

CompetitiveMultiple tools exist but differentiation opportunities remain

3 tools exist (Redis session store (DIY pattern), MCP 2026-07-28 RC official spec, Stainless SDK) but gaps remain: Not a product — it is an ad-hoc pattern that requires each team to write and maintain the session-bridge code themselves with no MCP-aware tooling, no protocol version negotiation, and no migration CLI.; Provides no backward-compatible adapter, no migration CLI, no session-bridge layer, and no tooling for the installed base of stateful MCP servers that cannot be immediately rewritten..

Competitive LandscapeFREE

Product	Does	Missing
Redis session store (DIY pattern)	Teams manually wire Redis as a shared session store so multiple MCP server instances can share session state; requires custom code per server.	Not a product — it is an ad-hoc pattern that requires each team to write and maintain the session-bridge code themselves with no MCP-aware tooling, no protocol version negotiation, and no migration CLI.
MCP 2026-07-28 RC official spec	Removes the stateful handshake at the protocol level so newly written servers are stateless by design.	Provides no backward-compatible adapter, no migration CLI, no session-bridge layer, and no tooling for the installed base of stateful MCP servers that cannot be immediately rewritten.
Stainless SDK	Generates MCP server SDKs and client libraries from OpenAPI specs.	Targets greenfield server creation, not stateless migration of existing stateful servers; no session externalization layer.
