@one-source/mcp

Unified MCP server for OneSource — 91 tools for blockchain data, live chain queries, Deepstate market data, The Standard Reserve, and REST API documentation in a single server.

What is MCP? The Model Context Protocol lets AI assistants call tools and access data sources. This server exposes both the OneSource blockchain API and its documentation as tools.

Quick Start

Claude Code

claude mcp add onesource -- npx -y @one-source/mcp@latest

Claude Desktop / Cursor

Add to your MCP config:

"mcpServers": { "onesource": { "command": "npx", "args": ["-y", "@one-source/mcp@latest"] } } }

Any MCP Client (stdio)

npx -y @one-source/mcp@latest

HTTP Server (self-hosted)

npx -y @one-source/mcp@latest --http

npx -y @one-source/mcp@latest --http --port=8080

Then connect your MCP client to http://localhost:3000/ (or your --port value, e.g. 8080 in the second example above).

Health check: GET http://localhost:3000/health (substitute your port).

`1s_block_number`	Latest block number
`1s_chain_id`	EIP-155 chain ID
`1s_contract_code`	Contract bytecode
`1s_ens_resolve`	ENS name/address resolution

Payments (2 tools)

Tool	Description

`1s_refund`	Reclaim an open payment channel's unspent deposit on demand — works for both an x402 `batch` channel (Base) and an MPP `session` voucher channel (Tempo)

Deepstate Market Data (10 tools)

Deepstate is an on-chain order-book protocol on Robinhood Chain (chain 4663). These tools read market data — order books, trades, candles, stats, maker analytics, and gas/depth analytics. They're ordinary tools on the same API and take no network parameter — always Robinhood Chain — and are paid like every other tool: API key, x402, or MPP. Since the DGP-3 migration (2026-09-22), maker rewards are per-market rather than a single fixed token — always check a market's reward_token on 1s_ds_markets rather than assuming DEEP.

Tool	Description
`1s_ds_markets`	List the Deepstate markets (order books) this API serves, with each market's slug, token layout, pool/router addresses, `status`, and `reward_token`
`1s_ds_book`	Order-book snapshot for a market — bids descending, asks ascending, with each price level's resting size
`1s_ds_trades`	Trade tape for a market, newest first — each fill's price, size, side, and block
`1s_ds_candles`	OHLCV candles for a market at a given timeframe
`1s_ds_stats`	Rolling 24h / 7d / 30d volume and price change for a market, plus the latest traded price
`1s_ds_makers`	Per-maker analytics for a market — time at top of book, resting notional, fill count/rate, and maker rewards earned (reward token is per-market — see `reward_token` on `1s_ds_markets`)
`1s_ds_cost_to_quote`	Gas spent resting and cancelling orders on a market, bucketed over time
`1s_ds_depth_history`	Depth heatmap for a market — resting order size by price level over time
`1s_ds_token_2deep`	2DEEP supply, cap, float, reward pool and endowment balances, migration liabilities, and pool price — live from chain
`1s_ds_migration`	DEEP/STATE-to-2DEEP redemption progress since DGP-3 (2026-09-22): totals, counts, remaining, and a daily series

Every Deepstate tool except 1s_ds_markets takes a book parameter: the market's canonical uppercase slug (e.g. NVDA-USDG) or its 32-byte book_id. Call 1s_ds_markets first for the full list.

The Standard Reserve (51 tools)

The Standard Reserve is an on-chain central-bank protocol on Robinhood Chain (chain id 4663). These tools read the deployed contracts' state as indexed and served by OneSource, with basis, as_of_block, and serving_state on every response. 1s_std_addresses and 1s_std_genesis_live are free; every other tool here is paid the same way as the rest of this API: API key, x402, or MPP. Several tools (1s_std_supply, _vaults, _pool, _exit_pressure, _backing, _policy_current) also take an atBlock param to read that state as of a past block instead of the latest one.

Tool	Description
`1s_std_addresses`	Verified registry of TSR contracts and pool, with a verification status per entry. Free, no payment required.
`1s_std_auction_days`	Per-day auction history for the license or charter auction: open/floor/close price, sold vs. offered, time to sell out; license days add purchase counts, distinct charters, average and total paid, and a purchases-per-transaction breakdown
`1s_std_auction_sales`	Recent sales for the license or charter auction, newest first: buyer, unit price, count, and block. Filter by kind, page with before/limit
`1s_std_auctions_current`	Current state of the daily license auction and charter auction: price, floor, sold/remaining today, phase, and last sale
`1s_std_backing`	Reserve backing: vault ETH balances, reserve-asset holdings, the vault's Uniswap v4 positions, and ETH backing per STANDARD in three variants: vault ETH only, with protocol-owned liquidity added, and with all reserve assets added at the Reserve's own pool prices (USDG at $1). Current, history, or as of a past block
`1s_std_branch_auction_live`	Raw head-fresh state of the Branch license auction: phase, price, today's sold/remaining counts, and recent sale velocity
`1s_std_branches_doi`	Days of Issuance for the Branch license auction, plus a buy-now-vs-wait table
`1s_std_branches_summary`	Summary across TSR's active Branches: count, issuance per Branch per day, and license price in days of issuance
`1s_std_buyback_readiness`	Contraction-vault buyback-tick readiness: this tick's ETH capacity, binding constraint, cooldown, TWAP deviation, and recent executed ticks
`1s_std_candles`	OHLC price candles for the ETH/STANDARD pool in ETH per STANDARD, with swap counts and volume. Set tf for candle width (1m to 1d) and from/to for the window
`1s_std_charter`	One charter by id, or charters filtered by owner: holder, branch count, mint kind, owed production, branch history, its share of the one-time charter stimulus (claimable by the charter's owner until a deadline returned in the response), and its share of each launchpad charter drop
`1s_std_decision_branch`	Composite: should I buy a Branch/license right now. Bundles Days of Issuance, license cost vs. the charter auction, recent auction history, policy outlook, pending governance changes, and what a branch earned in past launchpad charter drops (history, not a forecast)
`1s_std_decision_bid`	Composite: when would a standing license-auction bid at this max price be reached, how many bids and licenses are ahead of it, and (with `charter_id`) whether that charter's pending STANDARD and caps cover it. Fill is a separate transaction anyone may send; the response states that and the measured fill history. Takes `max_unit_price`; `count` and `charter_id` optional
`1s_std_decision_charter`	Composite: should I buy into a new charter right now. Bundles charter-auction state, license-cost cheapest path, Days of Issuance, backing ratio, holder concentration, and what a branch earned in past launchpad charter drops (history, not a forecast)
`1s_std_decision_exit`	Composite: should I exit a charter's branches right now. Bundles the exit quote, fee curve, fee forecast, tax schedule, pool state, policy outlook, pending governance changes, the unclaimed stimulus a full exit forfeits, and the charter drops closing would release, with a noteOwner warning
`1s_std_decision_hold`	Composite: should I keep holding STANDARD. Bundles the policy outlook, issuance runway, pending governance changes, tax schedule, buyback readiness, and dormancy state; takes no arguments
`1s_std_decision_plan`	Simulate three Branch-buying strategies (keep, selective, aggressive) over a horizon, seeded from live prices, issuance, and license cost unless overridden. With a charter id, launchpad drop shares appear beside the strategies and outside every ETH result. A planning tool, not a forecast: it never names a winning strategy

| 1s_std_decision_sbill | Composite: what should I do with this S-Bill. Before maturity: the exit payout now, the premium given up, and the exit fee on each coming day if nobody else exits (derived). After maturity: the redeem payout and what a roll would lock (derived), and the note th
