The to_mcp spec was describing one MCP tool per alknet operation — the tool-bloat problem. An LLM connecting to a node with 200 operations gets 200 MCP tools dumped into its context, degrading reasoning and wasting context budget. ADR-041 replaces this with the tool-gateway pattern (same pattern as opencode's memory and worktree tools): to_mcp exposes 4 fixed meta-tools (search, schema, call, batch) that gate access to the full operation registry. The LLM has a few tools in context, discovers operations on demand through search + schema, then calls. Same principle as Linux's man command — don't preload all documentation; query on demand. Gateway tool set: - search -> services/list (names + descriptions, AccessControl-filtered) - schema -> services/schema (full OperationSpec for a specific op) - call -> call.requested (Query/Mutation only, request/response) - batch -> multiple call.requested (correlated IDs, OQ-14) Subscription operations are excluded — MCP tool calls are request/response by protocol design (the client blocks until CallToolResult returns); streaming subscriptions don't fit. Subscriptions are filtered out of search results and cannot be invoked via call. http-mcp.md to_mcp section rewritten: the gateway tool set, Subscription exclusion, and the service behavior (tools/list returns 4 fixed tools, tools/call dispatches through the gateway). The 'Why' section adds the tool-bloat rationale and the memory/worktree tool pattern that informed the design. README/overview ADR tables and the top-level README current-state note updated for ADR-041.
Alknet
Status: Pre-alpha — This project is undergoing a major architectural pivot to an ALPN-as-service model. The previous implementation has been archived and a greenfield rebuild is in progress.
A self-hostable networking toolkit built on QUIC+TLS with ALPN-based protocol dispatch. Each protocol handler (SSH, SFTP, Git, HTTP, DNS, messaging, call protocol) registers an ALPN string on a shared endpoint. The ALPN negotiation during the TLS/QUIC handshake routes connections to the correct handler before any application bytes are read.
Core Insight
A service IS an ALPN. One endpoint, one port, many protocols — dispatched by the TLS handshake, not by application-level peeking or separate listeners.
