Janus โ UBOS Kinematic Drive concierge (MCP server)

Talk to Janus, the UBOS concierge, right inside your coding agent โ 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 โ so it cannot hallucinate. Each drive runs isolated on its own box; your data never leaves it.
โก Try the live test first โ 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 โ that's the engine your agent gets, pointed at your own repo.
Buy & pay โ for humans and agents
kinematic_checkout {email} โ 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} โ 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 โ no card, no signup, pure on-chain.
Why it's different
- Deterministic โ your files become typed "gear teeth"; a query meshes into them over exact candidates only. Same query โ same result, every time. Zero hallucination.
- Private โ one isolated drive per client, on its own box. Your data never touches a cloud LLM or any shared store.
- Fast โ a read-only mmap index + a tiny native scorer.

kinematic_provision | Request a private Kinematic Drive (managed onboarding). |
kinematic_checkout | Create a self-serve USDC order and receive Solana payment instructions. |
kinematic_checkout_status | Poll an order until payment clears and a provision token is ready. |
ubos_store_products | Discover the live UBOS pay-per-call agent tools and prices. |
ubos_store_call | Call a metered tool or receive self-describing HTTP-402 payment instructions. |
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 โ 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.
