Install in your client

Paste into the AI you're chatting with — it will figure out the rest

Please install the `claudesmalltalk` MCP server into my current AI client (that's you).

Required prerequisites (do these first if not already done):
- **Python 3.10+** — Python 3.10 or higher
- **Install uv** — Install the uv package manager (https://docs.astral.sh/uv/)
- **Squeak or Cuis Smalltalk** — Download a Squeak or Cuis Smalltalk VM and install the MCP server into the image (https://squeak.org/downloads/)
- **Clone ClaudeSmalltalk** — Clone the repo for smalltalk_agent_mcp.py Run: `git clone https://github.com/CorporateSmalltalkConsultingLtd/ClaudeSmalltalk` (https://github.com/CorporateSmalltalkConsultingLtd/ClaudeSmalltalk)
- **Create smalltalk-mcp.json config** — Copy examples/smalltalk-mcp-ollama.json (or a provider variant) and set vm.binary/vm.image paths

Canonical MCP server config (stdio transport):
- command: `uv`
- args: ["run","/path/to/ClaudeSmalltalk/smalltalk_agent_mcp.py"]
- required environment variables:
  - `SMALLTALK_MCP_CONFIG`: Path to your smalltalk-mcp.json config file (example: `/path/to/smalltalk-mcp.json`)

Note: Bridges Claude Desktop to a live Squeak/Cuis Smalltalk image. The `smalltalk_task` tool delegates work to a locally-configured LLM (Ollama, Anthropic, OpenAI, or xAI).

Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.
