## Caveats
- **Lowlevel-only.** `Server.middleware` on `mcp.server.lowlevel.Server` is the
one public hook; `MCPServer` has no public accessor for it yet (a
`MCPServer.middleware` accessor is planned before beta).
- **One list, two accessors.** `Server.middleware` on
`mcp.server.lowlevel.Server` is the hook this story uses; `MCPServer`
exposes the same list as `MCPServer.middleware` (or takes it at
construction as `MCPServer(name, middleware=[...])`).
- The middleware signature is **provisional** (see the TODO in
`src/mcp/server/lowlevel/server.py`): it tightens to a covariant `Context[L]`
and gains an outbound seam before v2 final.
`src/mcp/server/lowlevel/server.py`): it may change in a 2.x minor release,
tightening to a covariant `Context[L]` and gaining an outbound seam.
- `ServerMiddleware` / `CallNext` / `HandlerResult` are imported from
`mcp.server.context` (helper tier); not re-exported at `mcp.server.lowlevel`.
- Do **not** `await ctx.session.send_request(...)` while wrapping `initialize`
