v1.0.0-rc1: full MCP 2025-06-18 surface
Closes 14 issues; lmcp now implements the complete client-facing
surface of MCP spec 2025-06-18.
New primitives:
- fetch (#3) HTTP GET/HEAD with bounded body + render chain
- web_search (#4) pluggable backend (SearXNG/DDG/Tavily/Brave)
- Resources (#5) resources/list, /read, /templates/list + list_changed
- Prompts (#6) prompts/list, /get + list_changed
- Completion (#7) completion/complete for prompt/template args
- Logging (#8) logging/setLevel + notifications/message
- Sampling (#9) server-initiated sampling/createMessage
- Roots (#10) roots/list + cache + path_in_roots helper
Protocol / wire:
- Pagination (#12) cursor on tools|resources|prompts/list
- Structured tool output (#13) structuredContent + _meta + protoV bump to 2025-06-18
- Tool annotations (#14) readOnlyHint/destructive/idempotent/openWorld on all tools
- stdio transport (#15) LMCP_TRANSPORT=stdio for Claude Desktop / IDE clients
- Streamable HTTP (#16) select()-based event loop, sessions, persistent SSE,
DELETE, heartbeat, server-initiated request helper
- ping (#19) now emits result:{} not result:[] via json.empty_object
Cross-cutting fixes:
- json.lua: UTF-16 surrogate pair combination (emoji/non-BMP CJK round-trip)
- json.lua: json.empty_object sentinel for spec-correct {} emission
- handle_request: generic notification suppression (id==nil → return nil)
eliminates malformed -32601 with id:null on stdio and HTTP transports
Tool annotations backfilled across all registrations:
- server.lua: 10 tools (shell, shell_bg, read_file, write_file, edit_file,
list_dir, search_files, fetch, web_search, systeminfo)
- hub.lua: 8 remote_* tools
- example_server.lua: 4 demo tools + 3 sample resources + 1 sample prompt
+ 1 sample completer
Honest limits, filed as follow-up issues:
- #11 progress + cancellation — gated on #20 (handler concurrency)
- #18 windows/pkg sync — stale April-2026 snapshot, packaging decision
- #20 concurrent handler dispatch — select() loop concurrencies I/O, not
handler execution; synchronous tool
handlers still serialise (shell sleep 3
blocks a parallel ping)
Backwards compatible: every previously-deployed lmcp client (sessionless
POST, HTTP-only, no Mcp-Session-Id awareness) keeps working unchanged.
