Plan updated with the alknet-tty findings: the drainer pattern (single ordered writer) makes outbound chunk-boundary parsing sound; TestStdinSink's try_send→Full→Pending is the inbound backpressure precedent; OQ-01(a) now cites the reference. Task graph (taskgraph-validated, 17 tasks, 6 generations, no cycles): - tasks/server/: core-types, auth, healthz-decoy, adapter - tasks/gateway/: dispatch, routes, publish - tasks/websocket/: byte-adapter (research POC), upgrade-session, overlay-ops - tasks/adapters/: from-openapi, from-jsonschema, to-openapi, from-wss, mcp - tasks/client/: http-host - tasks/infra/: integration-suite (phase 4) Critical path runs through server core → adapter → WS session → overlay tests → integration suite. High-risk tasks are the three WS tasks, de-risked by the ws-byte-adapter POC blocking upgrade-session.

## Description
|
|
|
|
Port both MCP adapters from
|
|
`/workspace/@alkdev/alknet/crates/alknet-http/src/adapters/{from_mcp/`,
|
|
`to_mcp.rs}` behind the `mcp` feature (rmcp, streamable HTTP only —
|
|
ADR-037). from_mcp: tools/list discovery, per-tool HandlerRegistration
|
|
(Mutation, HandlerKind::Once, FromMCP leaf), structuredContent-preferred
|
|
output handling, ContentBlock-union fallback, isError→CallError.
|
|
to_mcp: 4 fixed gateway tools (search/schema/call/batch — Sub AND Pub
|
|
excluded), StreamableHttpService into axum under /mcp with bearer
|
|
middleware. Shared dispatch spine with to_openapi via GatewayDispatch.
|
|
|
|
## Acceptance Criteria
|
|
|
|
- [ ] Both adapters behind `mcp`; default features compile without rmcp
|
|
- [ ] from_mcp round-trip against a mock MCP server (tools/list, tools/call, structured + content-block outputs)
|
|
- [ ] to_mcp: 4 tools listed; call dispatch filtered by ACL; Pub/Sub ops excluded
|
|
- [ ] stdio transport not present anywhere (dependency audit)
|
|
- [ ] `cargo test --all-features` passes
