Janus — UBOS Kinematic Drive concierge (MCP server)

Talk to Janus, the UBOS concierge, right inside your coding agent — to get a private Kinematic Drive: a deterministic memory engine that gives your agent sub-millisecond, exact recall over your own private code & docs, with no LLM in the retrieval path — so it cannot hallucinate. Each drive runs isolated on its own box; your data never leaves it.

⚡ Try the live test first — no install

Open https://welcome-to-ubos.com and type a symbol (ThreadPoolExecutor, urlencode, JSONDecoder). You'll watch the real engine find the exact source in ~1ms, deterministically — that's the engine your agent gets, pointed at your own repo.

Buy & pay — for humans and agents (v0.1.3)

• kinematic_checkout {email} — self-serve USDC checkout: returns an order + pay instructions (Solana wallet, memo = order id, amount). kinematic_checkout_status {order_id} returns your provision token once paid.
• ubos_store_products / ubos_store_call {product, api_key, payload} — the UBOS x402 metered store: governor (constitutional reality-check, $0.005/call) and hotvessel (metered LLM, $0.01/call). No account: your first call returns HTTP-402-style pay instructions (USDC with memo = your api_key); pay, wait ~15s, retry.

Machines buying from machines — no card, no signup, pure on-chain.

Why it's different

• Deterministic — your files become typed "gear teeth"; a query meshes into them over exact candidates only. Same query → same result, every time. Zero hallucination.
• Private — one isolated drive per client, on its own box. Your data never touches a cloud LLM or any shared store.
• Fast — a read-only mmap index + a tiny native scorer.

Install

pip install ubos-janus-mcp

Claude Code

claude mcp add janus -- ubos-janus-mcp

Codex (~/.codex/config.toml)

[mcp_servers.janus]
command = "ubos-janus-mcp"

Gemini CLI (settings.json)

{ "mcpServers": { "janus": { "command": "ubos-janus-mcp" } } }

Works with Claude Code, Codex, Gemini CLI, Cline, Cursor — anything that speaks MCP.

How it works

This MCP server is a thin client: it proxies your agent's calls to the Janus concierge at JANUS_URL (default https://api.welcome-to-ubos.com/janus), which answers grounded on a live knowledge drive — the product, fronting the product. Your private data is never sent here; this is the storefront. Once you have a drive, you connect to it with the separate colony-gear MCP server.
