How do I install @usepolyglot/cli?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does @usepolyglot/cli need an API key?

No required environment variable is listed on this record.

What transport does @usepolyglot/cli use?

@usepolyglot/cli runs locally over stdio.

When was @usepolyglot/cli last checked?

Last checked 2026-10-28. A coding-agent CLI that works the same way whether the model is Claude, GPT, or an open-weight model like Qwen, DeepSeek, GLM, or Llama running locally.

FAQ

Questions

Why

Most agent CLIs lean on a provider's native function-calling API and assume near-perfect adherence to its exact tool-call JSON schema. Open-weight models frequently emit malformed, incomplete, or off-format tool calls against that API, so the whole agent loop breaks.

Polyglot treats tool invocation as a text-parsing problem instead: tools are described to the model in the system prompt, and a fault-tolerant streaming parser extracts and repairs tool calls from the model's raw output - trailing commas, single quotes, near-miss tool names, models that default to OpenAI-style {"name":..., "arguments":...} JSON instead of the taught envelope, all handled the same way. The same parser and executor run underneath every provider, so behavior doesn't silently diverge between "well-behaved" and "flaky" models.

Install

npm install -g @usepolyglot/cli

Or build from source - see the install guide.

Quick start

Point it at a local model (Ollama):

export POLYGLOT_PROVIDER=openai-compatible
export POLYGLOT_MODEL=qwen2.5-coder                # any model you've pulled
export POLYGLOT_BASE_URL=http://localhost:11434/v1 # default if unset
polyglot

Or Claude:

export POLYGLOT_PROVIDER=anthropic
export POLYGLOT_MODEL=claude-sonnet-4-5
export ANTHROPIC_API_KEY=sk-ant-...
polyglot
