What you get

The Obj-C runtime for LLM tooling

Selectors, dispatch tables, forwarding chains, method swizzling — applied to tool orchestration.

⚡

What it does

smallchat compiles tool definitions, embeds semantic fingerprints, and dispatches natural-language intent to the best-matching implementation — at runtime, with caching.

🎯

Why it matters

Tool proliferation is the next scaling problem. Routing by string matching breaks. Routing by semantic vector search does not. smallchat brings the Obj-C message dispatch model to LLM tooling.

Deep dive

SelectorTable, DispatchContext, OverloadTable, ResolutionCache, ToolClass hierarchies, method swizzling, streaming tiers, and the MCP 2025-11-25 server — all documented.

New in 0.4.0

MCP Tool Registry & Manifest Builder

115+ MCP packages

Pre-compiled servers from GitHub, Slack, Stripe, Docker, Notion, Postgres, and more — searchable by category.

Cart-style builder

Select the tools you need, compile a single manifest, and download — no account required.

Anonymous compile API

POST /api/compile merges any packages into one dispatch-ready JSON artifact.

Primitives, not a framework

Why not LangChain?

smallchat gives you the dispatch layer. You build the agent. No abstractions you didn't ask for.

Concern	LangChain	smallchat
Streaming	CallbackManager + custom piping	`for await` over native provider deltas
Tool dispatch	Chain/Agent hierarchy	One `smallchat_dispatchStream` call
Caching	External wrappers	Built-in resolution cache
Extensibility	Subclass and register	`toolClass.addMethod` or swizzle
Bundle size	Multiple adapter packages	< 5 MB, zero dependencies
