A workspace for agent-made artifacts — documents, plans, decks, and fully-styled pages with durable URLs, version history, comments, editing, and optional review.

Publish agent output to permanent versioned URLs, read review comments back, and revise.

Publish anything your agent makes to a permanent versioned URL, read the review comments back, and revise, all without leaving the session. Chats scroll away. Artifacts stay. Derive is the system of record for the work your agents produce: publish a fully-styled page, document, deck, or dashboard to a permanent versioned URL, hand it to a human, and pull their comments back into the next revision. Vendor-neutral and model-agnostic: any agent that speaks MCP can use it. OAuth 2.1 with dynamic client registration, so there is no key to paste. Free tier is 3 editors with no card, and it self-hosts as a single container under a fair-source licence for teams that cannot send work to a hosted service.

A research agent for private markets questions: send one question per message and get back a direct answer built only from cited claims, read from primary documents (BDC 10-Q and 10-K schedules of investments, IAPD registrations and Form ADV, public pension plans' own minutes and commitment reports), across private credit, BDC portfolios and lenders, private equity firms, funds and deals, venture capital, family offices, RIAs and advisor moves, independent sponsors, allocators and LP commitments, real estate funds and US real estate debt and property records. Facts carry their source and observation date, and every answer states OK, NO_MATCH, NOT_COVERED or UNKNOWN rather than guessing. Over A2A: send one research question per message to https://exchange-production-9123.up.railway.app/a2a (JSON-RPC; A2A 1.0 and 0.3 methods). Without a DFX plan, list answers name the first rows and count the rest, and contact values are never returned. Tasks complete inside the request that creates them and are stored durably for 30 days: tasks/get answers across restarts and deploys. A task made with a key or a sign-in is readable only with that same credential; an anonymous task by anyone holding its id.

Private credit: lenders, sponsor financing, credit facilities, BDC holdings, LP allocations. Cited.

MCP Analytics is a Model Context Protocol server that answers business and statistical questions about your data, as deep as each question needs. - Answer: a quick question about the data, read from all of it, shown with how we got it, and saved. - Analytics: a tested statistical method runs on the data, and we interpret it with charts and a written report. - Custom Analytics: a question only your business asks, built for your data from proven models, yours to re-run on next month's file. Analytics is repeatable: same data, same numbers. Every report names its method and the code that ran it, and runs again on new data. Start with the path_resolver tool. It is for business and statistical questions about data, not a general-purpose assistant.

Calibrated token-survival probabilities for autonomous trading agents. Keyless by design: no signup, no API key — pay per call in USDC (x402). /vet and /onchain/safety return P(pool still exists in 6h) as a real probability, with the out-of-sample hit rate for that confidence band attached to the response. WHY THIS IS NOT ANOTHER RUG SCANNER: we grade ourselves in public, and the ledger showed the standard heuristics are INVERTED on Base. Across 1,022 graded tokens, 'ownership renounced' rugged 77.5% while NOT-renounced rugged 4.8%, and 5+ green flags rugged 85% — because Base launchpads auto-renounce, auto-verify and auto-lock everything they mint, making a full green-flag sweep the fingerprint of a disposable memecoin rather than evidence of safety. Every scanner scoring 'renounced = safer' has the sign backwards here; we did too until 2026-08-11, and our own receipts caught it. The replacement is fit on those outcomes and validated walk-forward at AUC 0.954 across 6 chronological folds (retired scorer: 0.545). Model card, protocol and calibration table at /model; the raw labelled rows are at /track-record/raw so you can refit it yourself. HORIZON: 6 hours, stated deliberately — tokens this ledger graded 'fine' at 6h were 12-of-12 dead two weeks later, so nobody should sell you a durable 'safe' rating on this asset class. Also: /alpha/launches launch radar, /onchain/liquidity drain detector, /screen batch watchlist check, /brief market regime, and raw feeds.
