Now Dwell — The Carbon DeFi MCP Server
In February, Bancor Undertaking Lead Dr. Mark Richardson mentioned Carbon DeFi wanted to lean as exhausting as attainable into the rising agent paradigm. At the moment, that’s not a place — it’s a stay product.
With the Carbon DeFi MCP server, any MCP-compatible agent can now connect with Carbon DeFi, discover the protocol, construct methods, and handle positions — all by way of plain language, all with the consumer signing each transaction.
To indicate what that appears like in apply, Claude was related on to the Carbon DeFi MCP server and requested to construct a full presentation from what it discovered. No directions on what to incorporate, no guide information entry — simply Claude, the stay server, and 25 instruments to discover.
25 instruments. 5 chains. 6 technique sorts. Zero gasoline on fills for makers.
It covers the complete lifecycle of interacting with Carbon DeFi — from market analysis and simulation by way of onchain buying and selling technique creation, place administration, and taker swaps. The whole lot an agent must go from a consumer’s acknowledged intent to a signed transaction.
Overview — What’s the Carbon DeFi MCP?
Claude introduces the Carbon DeFi MCP precisely, defining it as a stay, open endpoint that provides any AI agent the power to know Carbon DeFi, work together with it, and assist customers create and handle onchain buying and selling methods — by way of plain language.
It goes on to focus on three predominant factors:
The agent prepares. The consumer indicators. The agent by no means submits something to the chain. Funds and personal keys stick with the consumer always — no exceptions.It’s self-describing. Brokers pull the complete device spec on connection and orient themselves mechanically. No guide integration work past the config entry.It validates earlier than it fingers something to the consumer earlier than any points turn out to be signed errors. Each response features a warnings array that surfaces points reminiscent of a promote worth set beneath present market, a finances too small for an outlined vary, or a reproduction place.
Structure Overview — Six useful teams. 25 instruments.
The 25 instruments break into six teams, every dealing with a definite section of interplay with the protocol.
Learn (2 instruments) — Verify Positions
• Fetch all lively methods for a pockets. • Lookup any technique by ID, standing, proprietor, costs, budgets, and lifelong commerce historical past.
Create (5 instruments) — Construct Methods
Six sorts out there, every suited to a unique buying and selling intent.• Restrict orders • Vary orders• Recurring buy-sell (restrict and/or vary)• Concentrated liquidity• Full vary liquidityThe agent determines the proper sort, builds the transactions, and returns it unsigned.
Handle (7 instruments) — Management stay positions
• Reprice• Edit technique sort • Deposit further funds• Withdraw full or partial funds• Pause and resume buying and selling• Shut a technique
Discover (8 instruments) — Analysis the market
• Protocol stats• Worth historical past• Pair liquidity• Alternative discovery• Token resolutionThe Carbon DeFi MCP stories the present state of the protocol, not static documentation.
Commerce (2 instruments) — Swap as a taker
• Get quotes in opposition to Carbon DeFi’s present maker liquidity.For customers desirous to commerce immediately, the agent routes execution reasonably than construct positions.
Assist (2 instruments) — Study and information
Brokers clarify:• What they’re doing• Why they’re doing itThe MCP supplies per-tool steering and protocol schooling.
Create. Six methods to specific a place.
Every technique sort maps to a unique sort of buying and selling intent. The agent determines the proper sort from what the consumer describes.
Restrict order — one-time at actual worth
• Purchase or promote at a single fastened worth. • Executes in full when the market reaches that stage. • Non-custodial, onchain, no centralized counterparty, and no expiry.
Vary order — gradual execution
• Distributes execution progressively throughout a worth band. • Helpful for scaling in or out of a place. • Permits the gradual accumulation or distribution reasonably than figuring out a single worth level.
Recurring technique — looping purchase + promote, zero gasoline on fills ★
• Named probably the most highly effective of the Carbon DeFi unique options. • Purchase and promote ranges are outlined independently. • When the purchase facet fills, proceeds rotate to the promote facet mechanically — and again once more when the promote facet fills. • The technique continues executing for so long as the market trades within the outlined vary. • Zero gasoline value for makers on stuffed orders. • No additional consumer enter required per cycle.
Concentrated technique — two-sided liquidity with unfold
• Two-sided liquidity inside a customized unfold/price tier and customized vary to purchase and promote. • Auto-compounding • No tick constraints
Full-range technique — covers as much as 1000x from present market worth
• The customized unfold share defines the hole between purchase and promote sides.
Taker swap — route in opposition to maker liquidity
• Brokers get quotes and construct swap transactions in opposition to present Carbon DeFi maker liquidity, construct the unsigned swap transaction, and current it to the consumer to signal. • For conditions the place quick execution issues greater than precision and worth certainty.
Constructed-in solver system. Chainwide. Operating 24/7.
Each technique created on Carbon DeFi — restrict, vary, recurring, concentrated, full vary — is broadcast to your entire blockchain the second it goes stay. It’s open and fillable by anybody: different merchants, bots, and Carbon DeFi’s built-in solver system, which runs constantly and pulls liquidity from all main DEXs on the identical chain.
The solver is constructed on Marginal Worth Optimization, a brand new strategy developed by Bancor that delivers a 200x enchancment in execution pace over beforehand printed arbitrage algorithms. It operates throughout a number of modes — pairwise, triangular, and multi-hop arbitrage — dynamically adjusting to real-time market circumstances throughout 90+ integrations on 10 blockchains. The solver system helps effectively fill orders and maintain methods actively buying and selling. Customers should not counting on a single liquidity supply or a restricted variety of resolvers.
The Recurring Technique. Why that is Carbon’s strongest device for brokers.
Claude created a devoted slide for the recurring technique, naming it Carbon DeFi’s strongest device for brokers — and the one most related to agent-based buying and selling.
Uneven Ranges
Ex. “Purchase ETH between $2600-$2800, promote between $3200-$3500. Preserve it working.”
• Purchase and promote ranges are fully unbiased, non-overlapping orders. • An agent might be aggressive on one facet and conservative on the opposite — no pressured symmetry.• Fund one or each orders, relying on the place you assume the market’s headed first. • Customized unfold
Automated Rotation
• When the purchase facet fills, proceeds transfer to the promote facet. • When the promote facet fills, they transfer again to purchase. • The technique manages itself, constantly buying and selling so long as the market worth is throughout the decided worth ranges.
Zero gasoline per fill
• And takers pay gasoline on Carbon DeFi — makers don’t. • Operating a recurring technique has a essentially totally different value construction than something requiring per-fill gasoline funds.
Key Differentiators
Swapping as a taker on an AMM • Pay protocol and gasoline charges per transaction.• Incurs slippage, leading to zero worth certainty • Susceptible to sandwich assaults• Requires manually executing multiples trades• Unable to pre-set trades.
Putting an order by way of a unique onchain orderbook-style DEX• Proof against MEV sandwich assaults• Orders expire• Permissioned system with orders out there to solely a choose variety of takers/resolvers.• Not absolutely onchain • Not adjustable • One order should fill in an effort to manually create one other with the proceeds.
Carbon DeFi• 100% worth certainty. Makers obtain the precise quantity they quoted.• Fully Resistant to MEV sandwich assaults• Pre-set trades to execute at a customized worth or inside a customized worth vary• No expiry• Absolutely onchain• Assist partial fills• Adjustable. No must cancel and recreate.• One-time gasoline price upon creation• Doesn’t require guide intervention. Automated cyclic nature of purchase low, promote excessive, repeat.
Handle. Full lifecycle management with out touching the app.
Seven administration instruments cowl every little thing that occurs after a technique goes stay.
reprice_strategy — replace the purchase or promote worth rangesedit_strategy — Change a technique from one sort to a different — a restrict order to a variety order, a recurring technique to a concentrated technique, any sort to every other sort.deposit_budget — add capital to an present technique with out recreating it.withdraw_budget — pull funds, full or partial, with out closing the place — permitting for future use of the technique with out having to restart totally.pause_strategy — freeze buying and selling; costs zeroed, funds keep within the technique.resume_strategy — restore worth ranges and proceed actively buying and selling.delete_strategy — completely shut and return all funds to the pockets.
All seven return unsigned transactions. The consumer indicators each motion.
Discover. Dwell protocol intelligence — not static docs.
Eight discover instruments give brokers entry to real-time and historic protocol state. The distinction between a generic AI explainer and an MCP-connected agent is that the agent can reply “what’s taking place proper now” — not simply “what’s Carbon DeFi.”
1. get_strategies
all lively methods for a pockets on any supported chain, at present together with Ethereum, Sei, Celo, COTI, and TAC.
2. get_strategy
full particulars on any technique by ID, sort, standing, proprietor, costs, budgets, lifetime fill rely.
3. get_activity
commerce and occasion historical past, filterable by motion sort and time window.
4. explore_pair
Carbon DeFi market liquidity and prime lively methods for any token pair.
5. find_opportunities
low cost buys and premium sells, the place makers are positioned considerably away from the market worth reported.
6. get_protocol_stats
TVL, quantity, and price historical past. As much as 30 days per chain.
7. get_price_history
historic OHLC (open, excessive, low, shut) worth information for any token pair. Powers simulation and analysis.
8. resolve_token
converts any token image (“USDC”, “wrapped ether”, “WBTC”) to the right onchain contract tackle for the proper chain. Brokers and customers by no means contact contract addresses immediately.
Simulate. Backtest earlier than any capital goes onchain.
Claude refers back to the simulation device as probably the most underused functionality within the MCP and some of the invaluable.
Earlier than any capital is dedicated, an agent can backtest a technique configuration in opposition to actual historic worth information as much as one year. Provide a token pair, a time window, worth ranges, and budgets — the device returns simulated fills, returns, and cycle counts for recurring and concentrated technique sorts.
The workflow: generate two or three candidate configurations, run simulation on every, evaluate outcomes, suggest the perfect match for the consumer’s acknowledged threat tolerance — then and solely then construct the transaction.
Design rules. 4 conventions that govern each device.
4 conventions govern how each device within the MCP behaves. Price understanding earlier than constructing on prime of it.
Unsigned at all times.
Each write operation returns an unsigned transaction. The agent by no means submits something to the chain. Funds and personal keys by no means go away the consumer’s management.
Verify the warnings array.
Each response consists of one. Verify it earlier than presenting a transaction — it surfaces points earlier than they turn out to be signed errors.
get_strategies earlier than creating.
At all times test present positions earlier than constructing or modifying a technique. It prices one name and avoids duplicate positions or edits in opposition to stale state.
Costs in quote per base.
All costs are quote token per one base token. The purchase finances is at all times within the quote token. The promote finances is at all times within the base token. Market worth is auto-fetched from the Carbon DeFi API — brokers don’t provide it manually.
Chain protection. 5 chains, one interface.
The MCP covers each chain the place Carbon DeFi has its personal deployment: Ethereum, Celo, Sei, TAC, and COTI. Chain choice is dealt with mechanically — no guide contract addresses, no switching between interfaces.
An agent related to the MCP can evaluate liquidity throughout all 5 chains from a single connection, floor the place pairs are most lively, and route accordingly.
Some examples of stay numbers brokers can entry: TVL throughout the 5 chains, quantity over a specified time interval, lifetime trades per token pair, and variety of lively methods throughout a buying and selling pair.
Getting Began. Join in below a minute.
The Carbon DeFi MCP works with any MCP-compatible agent — Claude Desktop, Claude Code, ChatGPT, Cursor, Windsurf, Cline, VS Code with GitHub Copilot, Nimbalyst, and any framework supporting the Mannequin Context Protocol customary. Right here’s the way to join it in Claude Desktop.
Earlier than you start: ensure you have Claude Desktop put in and Node.js in your machine. You may test Node.js by opening a terminal and working node — model. If nothing comes again, obtain the LTS model from nodejs.org first.
Step 1 — Open your config file. In Claude Desktop, click on the Claude menu in your system menu bar (not contained in the app window) and go to Settings → Developer → Edit Config. This opens the claude_desktop_config.json file. If it doesn’t exist but, Claude Desktop will create it for you.
The file can also be at these paths if you wish to open it immediately:
macOS: ~/Library/Utility Assist/Claude/claude_desktop_config.jsonWindows: %APPDATApercentClaudeclaude_desktop_config.json
Step 2 — Add the Carbon DeFi server. Paste the next into the file. If the file already has different MCP servers in it, add the “carbon-defi” entry inside the prevailing “mcpServers” block reasonably than changing the entire factor.
Step 3 — Save and restart. Save the file, then absolutely give up and relaunch Claude Desktop. All 25 Carbon DeFi instruments can be found instantly. Clicking the instruments indicator within the chat enter reveals the complete record of what’s related.
For different brokers and frameworks: the complete OpenAPI spec is at mcp.carbondefi.xyz/openapi.json, a ChatGPT plugin manifest at mcp.carbondefi.xyz/.well-known/ai-plugin.json, and direct REST entry at mcp.carbondefi.xyz/instruments/:toolName. The server can also be listed on mcpservers.org and clawhub.ai for discovery.
Leaning into the agent financial system.
In February, Bancor Undertaking Lead Dr. Mark Richardson mentioned it plainly: brokers will more and more act on behalf of customers, protocols must be constructed for that actuality, and Carbon DeFi must lean into it as exhausting as attainable. This walkthrough isn’t a demo surroundings or a curated dataset — it’s the results of ‘leaning into it’ — the precise server, the precise instruments, and the precise protocol information.
