turnstone 0.9.8

Multi-node AI orchestration platform with tool use, agent routing, and cluster simulation.

Turnstone

Multi-node AI orchestration platform. Deploy tool-using AI agents across a cluster of servers with direct HTTP routing, interactive interfaces, and enterprise governance.

Beta — Use at your own risk. APIs, configuration formats, and database schemas may change between versions without migration paths.

Named after the Ruddy Turnstone (Arenaria interpres) — a shorebird that flips stones to discover what's hiding underneath.

What it does

Turnstone gives LLMs tools — shell, files, search, web, planning — and orchestrates multi-turn conversations where the model investigates, acts, and reports.

• Interactive sessions — terminal CLI or browser UI with parallel workstreams
• Cluster dashboard — real-time view of all nodes and workstreams with console routing proxy
• Intent validation — LLM judge evaluates every tool call with risk assessments and evidence
• Governance — RBAC, OIDC SSO, tool policies, skills, usage tracking, audit logs
• Multi-provider — OpenAI-compatible APIs (vLLM, llama.cpp, NIM) and Anthropic Messages API
• MCP support — external tool servers with native deferred loading (Anthropic/OpenAI) or BM25 fallback

Quickstart

pip install turnstone

# Terminal REPL
turnstone --base-url http://localhost:8000/v1

# Browser UI
turnstone-server --port 8080 --base-url http://localhost:8000/v1

# Cluster dashboard
pip install turnstone[console]
turnstone-console --port 8090

Docker

cp .env.example .env  # edit LLM_BASE_URL, OPENAI_API_KEY, etc.
docker compose --profile production up

See QUICKSTART.md for the bootstrap wizard and docs/docker.md for Docker configuration and profiles.

Programmatic (SDK)

from turnstone.sdk import TurnstoneServer

with TurnstoneServer("http://localhost:8080", token="tok_xxx") as client:
    ws = client.create_workstream(name="demo")
    result = client.send_and_wait("Analyze the error logs", ws.ws_id, auto_approve=True)
    print(result.content)

Tools

Built-in tools for shell, files, search, web, memory, notifications, and autonomous sub-agents — plus external tools via MCP with native deferred loading. See docs/tools.md for the full reference and docs/mcp.md for MCP configuration.

Architecture

Single-node: Client → Server (direct HTTP + SSE). No external dependencies beyond the database.

Multi-node: Client → Console (hash ring routing proxy) → Server nodes. The console maintains a 65536-entry bucket cache for O(1) workstream routing. A rebalancer daemon redistributes buckets when nodes join or leave.

Component	Purpose
turnstone	Terminal CLI (REPL)
turnstone-server	Web UI + REST API + SSE events
turnstone-console	Cluster dashboard + routing proxy + admin panel
turnstone-channel	Channel gateway (Discord, with adapters for Slack/Teams planned)
turnstone-admin	User/token management CLI
turnstone-eval	Eval harness for prompt/tool optimization
turnstone-bootstrap	LLM-guided setup wizard
