Skein Toolkit Server

A repo-agnostic clone of the AI development toolchain originally built inside Electron-Splines: a Cloudflare Workers AI proxy, a multi-step task orchestrator, and a local agentic MCP server, fronted by a unified LiteLLM proxy.

This repo is the result of the "LLM Tech Stack Standalone Repository" spin-off (see architecture-docs/global/ai-task-queue.md, AT-1116-1139, in the Electron-Splines repo for the full task history and rationale). Further refinement of this agentic system happens here, not in Electron-Splines.

What's in here

Path	Purpose
mcp-server/local-mcp.py	The core: a local MCP SSE server (port 3100) that also proxies/instruments Cloudflare Workers AI requests at /cfproxy/{account_id}/..., including a multi-step task orchestrator with bounded-ambiguity escalation.
mcp-server/devserver-mcp.py	A lighter MCP server variant for a remote GPU devserver.
mcp-server/litellm_config.yaml + litellm.env.example	LiteLLM unified proxy config routing local/CF/Groq/DeepSeek/Anthropic/OpenAI models.
mcp-server/run-cline.ps1, resume-orchestrator-run.ps1, toolchain-doctor.ps1, start-litellm.ps1	Launcher/diagnostic scripts for running Cline against this stack on Windows.
cloudflare/README.md	Cloudflare Workers AI configuration (env-var only -- no zone/firewall config).
docker-compose.yml, docker-compose.override.yml, docker/	Containerized mcp-server + LiteLLM stack.

Quick start (local, Windows)

1. Create a Python virtualenv at the repo root and install dependencies:

   python -m venv .venv
   .venv\Scripts\pip install -r mcp-server\requirements.txt
   

2. Copy mcp-server\litellm.env.example to mcp-server\litellm.env and fill in your API keys (see cloudflare/README.md for the Cloudflare token).
3. Run mcp-server\toolchain-doctor.ps1 to diagnose and (where possible) auto-start LiteLLM and local-mcp.py.
4. Run mcp-server\run-cline.ps1 -Task "..." to launch Cline against the configured model.

By default, local-mcp.py operates on the parent of the mcp-server/ directory (i.e. this repo's checkout). Set WORKSPACE_ROOT to point it at a different project checkout instead.

Quick start (Docker)

cp docker/.env.example docker/.env   # fill in API keys
docker compose up --build

This starts mcp-server (port 3100) and litellm (port 4000, dashboard at /ui). By default mcp-server operates on ./workspace -- use docker-compose.override.yml to mount a different project checkout.

Environment variables

Variable	Default	Purpose
WORKSPACE_ROOT	parent of mcp-server/	Project checkout local-mcp.py reads/writes/runs commands in.
CF_API_BASE / CF_API_KEY	--	Cloudflare Workers AI proxy target + token. See cloudflare/README.md.
CF_PROXY_OQ_LEDGER_PATH	architecture-docs/global/architect-open-questions.md	Path (relative to WORKSPACE_ROOT) to an "open questions" ledger the orchestrator appends bounded-ambiguity rows to. If the consuming project has no such ledger, leave the default -- failures to read/write it are logged and degrade to "ambiguity surfaced inline", not a crash.
CF_PROXY_USD_TO_AUD_RATE, CF_PROXY_MONTHLY_BUDGET_AUD, CF_PROXY_DAILY_REVIEW_THRESHOLD_USD	1.42, 100.00, derived	CF spend-review accounting (optional).

Status

This is an early-stage clone (Phase 1 of the migration plan in planning_document.md): the toolchain runs standalone, but the orchestrator's "open questions" / "actionable tasks" governance integration (CF_PROXY_OQ_LEDGER_PATH and friends) still assumes an Electron-Splines-style architecture-docs/ layout when enabled. Generalizing that integration into reusable create_open_question / create_actionable_task MCP tools is tracked as AT-1137-1139 in the source repo.

Full mirroring of the consuming project's app/, engine/, and scripts/ directories (AT-1117/1118/1119) has not been done here -- this clone currently contains only the AI-toolchain pieces (MCP server, orchestrator, LiteLLM, Cloudflare/Docker config). If the original AT-1117/1118 scope (mirroring the entire Electron-Splines app and engine source trees into this repo) is still wanted, that is a separate, much larger effort and should be re-scoped with the architect first.
