Ask Claude or ChatGPT who bought a token this morning, or where the money from last week\u2019s hack went. You will get one of two replies. Either the chatbot says it cannot see live data, or it gives a confident answer it made up. The AI learned from a snapshot of the web, and it has never read a\u00a0block.<\/p>\n
Disclosure: I wrote this story with help from an AI writing tool. Figures come from each vendor\u2019s own docs and from my own test runs, all checked on 6 October\u00a02026.<\/em><\/p>\n Short answer:<\/strong> the best crypto MCP server for blockchain data analysis in 2026 is Bitquery MCP. It puts DEX trades, trader profit and loss, fund tracing on 19 chains and wallet labels in one server that works in Claude, ChatGPT and Cursor. Pick Dune for custom SQL, Nansen for Smart Money labels, Etherscan for free wallet lookups and CoinGecko for\u00a0prices.<\/p>\n A crypto MCP server is a plug-in that gives an AI assistant, such as Claude or ChatGPT, live tools for reading blockchain data. MCP stands for Model Context Protocol<\/a>, an open standard for connecting assistants to outside tools. The server hands the assistant tools such as \u201clist this wallet\u2019s transfers\u201d or \u201crank the top traders of this token\u201d. You ask in plain English. The AI picks a tool, reads the rows that come back and writes the\u00a0answer.<\/p>\n The servers differ in what those tools can reach. Some return token prices. Some return raw node data that a developer reads. A few return the analysis itself: who traded a token, who made money on it, where funds moved and who owns the wallet at the other\u00a0end.<\/p>\n I scored each server on four questions:<\/p>\n Depth.<\/strong> Does it return the rows behind an answer, each trade and each transfer, or only\u00a0totals?Analysis tools.<\/strong> Can it follow money, label wallets and rank traders without you writing\u00a0code?Coverage.<\/strong> How many chains does it reach, and does that include Bitcoin, Solana and\u00a0Tron?Setup and price.<\/strong> Is it hosted with a browser sign-in, or a local install with keys? What does it cost per\u00a0month?<\/p>\n I also ran Bitquery on three real questions on 6 October 2026. The answers are in its section\u00a0below.<\/p>\n Bitquery MCP<\/strong>, best overall for on-chain analysis: 10 chains for DEX data, 19 for fund tracing, 314 tools, browser sign-in, from $19 per\u00a0month.Dune<\/strong>, best for custom SQL: 100+ chains, 26 tools, OAuth or API key, paid in Dune API\u00a0credits.Nansen<\/strong>, best for Smart Money labels: 50 tools (12 through a connector), Nansen Pro from $49 per month billed yearly, with 2,000 API credits per\u00a0month.Etherscan<\/strong>, best free option for EVM lookups: 60+ EVM chains, 21 tools (16 with no key), free to\u00a0start.CoinGecko<\/strong>, best for prices: 2 tools that reach 100+ API methods, free public server with no key, Pro plans for higher\u00a0limits.Alchemy<\/strong>, best for app developers: 100+ chains, 168 tools, browser sign-in, free plan with 30M compute units per\u00a0month.Blockscout<\/strong>, best for explorer data on 100+ chains: 16 tools, free PRO API key with 100,000 credits per\u00a0day.<\/p>\n Bitquery MCP<\/a> is a hosted server at mcp.bitquery.io. You sign in with a Bitquery account in your browser (OAuth 2.1), so there is no API key to paste. It works in Claude (desktop, web and Claude Code), ChatGPT, Cursor, VS Code, OpenAI Codex and Windsurf.<\/p>\n Most on-chain questions come down to two questions: who is trading this token, and where did the money go? Bitquery sits at number one because it has dedicated tools for both. DEX trades and trader rankings answer the first. Hop-by-hop fund tracing answers the second, with labels on the wallets at the end. No other server on this list has a built-in tool that follows funds hop by hop across Bitcoin, Tron and the EVM\u00a0chains.<\/p>\n DEX data on 10 chains.<\/strong> Ethereum, Arbitrum, Base, Polygon, Optimism, BNB Chain, Tron, Solana, Robinhood Chain and Arc, Circle\u2019s new chain. Tools cover trending and new tokens, price candles down to one second, pool trades, top traders and trader profit and\u00a0loss.Fund tracing on 19 chains.<\/strong> The same 10, plus Bitcoin, Litecoin, Dogecoin, Bitcoin Cash, Dash, Zcash, Cardano, the XRP Ledger and Stellar. You can follow funds hop by hop with Bitquery MCP<\/a> and get a summary of who an address sends to and receives\u00a0from.Address labels.<\/strong> Exchange deposit wallets, mixers, scams, darknet markets and token clones, so a trace ends at a name instead of a string of\u00a0hex.Risk screen.<\/strong> Ask whether an address is risky and it returns LOW, MEDIUM or HIGH with the evidence behind the\u00a0verdict.Polymarket and Hyperliquid.<\/strong> 14 tools for prediction-market odds, trades and holders, and 18 for Hyperliquid prices, funding, liquidations and trader positions.SQL.<\/strong> The $149 plan adds raw SQL over 30 days of per-second trades.<\/p>\n In total, the server listed 314 tools when I counted on 6 October\u00a02026.<\/p>\n What it returned when I tested it.<\/strong> On 6 October 2026, I connected Bitquery to Claude and asked three questions.<\/p>\n \u201cWhat are the most traded Polymarket markets today?\u201d<\/em> The top market over the 24 hours to 13:33 UTC was \u201cWill Sweden win on 2026\u201310\u201305?\u201d, with $4.17 million traded across 2,846 orders from 274 wallets. The answer also said its order data ran 17 minutes behind the\u00a0clock.\u201cWhat are the top Base tokens by DEX volume in the last 24 hours?\u201d<\/em> Doppler (XDP) led with $260 million traded, more than its $202 million fully diluted value. Volume above a token\u2019s total value is a reason to check for wash trading before you trust the figure. The same list held a copycat token named \u201cOpenAI\u201d that lost more than 99% of its price in those 24\u00a0hours.Following stolen funds.<\/em> I started from a wallet that held SOL drained from TradeWiz users on 30 September. One tracing call showed it sent 191 SOL on 1 October to a single address, and a label lookup tagged that address as a KuCoin deposit address. Bitquery\u2019s TradeWiz drain investigation<\/a> has the full\u00a0trail.<\/p>\n Price.<\/strong> The Trading MCP plan costs $19 per month for 32 tools: trending tokens, candles and top traders. The AI Investigation plan costs $149 per month and opens all 314 tools, including labels and raw SQL. Yearly billing brings them down to $13 and $100 per month. A 7-day trial gives you 100\u00a0credits.<\/p>\n Watch out for.<\/strong> DEX data covers 10 chains, so a token that trades only on Avalanche or Sui needs another server, such as Dune. The $19 plan is for trading data only; tracing, labels and SQL need the $149\u00a0plan.<\/p>\n Best for:<\/strong> investigators, compliance teams and traders who want market data and money trails in the same\u00a0chat.<\/p>\n Dune<\/a> launched its official MCP server in early 2026. It connects the AI to Dune\u2019s data warehouse, which holds more than 100 indexed chains, decoded smart contracts and tables built by Dune\u2019s community.<\/p>\n Dune\u2019s docs list 26 tools. They let the assistant search for tables, write and run SQL queries, and turn the results into charts and dashboards. You sign in with OAuth or a Dune API key, and calls draw on your Dune API\u00a0credits.<\/p>\n Watch out for.<\/strong> Every answer is a SQL query that the AI writes against tables it first has to find. When the query is right, you get any metric you can think of. When it is wrong, you debug SQL. Long queries can also run past a client\u2019s time limit; Dune\u2019s own docs flag the 60-second default in OpenAI\u00a0Codex.<\/p>\n Best for:<\/strong> analysts who already know Dune and want a custom metric or a dashboard.<\/p>\n Nansen\u2019s server<\/a> is built around its wallet labels. Connect through a connector with your Nansen login and you get 12 curated tools. Connect with an API key and you get the full set of 50, covering Smart Money holdings and trades, token flows, buyers and sellers, wallet profit and loss, related wallets, Hyperliquid positions and prediction markets.<\/p>\n Price.<\/strong> Nansen Pro costs $69 per month, or $49 per month billed yearly, and tops your API credits back up to 2,000 each month. Most tool calls cost 1 to 5 credits. Label lookups cost the most, from 100 to 500 credits per\u00a0call.<\/p>\n Watch out for.<\/strong> The label tools are Nansen\u2019s main draw, and they cost the most: 2,000 credits buy about 20 common label lookups. On a free key the premium label tools return an upgrade error. Nansen\u2019s docs also say coverage varies by chain and by\u00a0tool.<\/p>\n Best for:<\/strong> traders who want to see what large, labelled wallets are\u00a0buying.<\/p>\n Etherscan\u2019s official server<\/a> runs at mcp.etherscan.io with 21 tools across more than 60 EVM chains. They cover balances, transactions, token transfers, contract source code, gas prices and event logs. A keyless version runs 16 of those 21 tools with no sign-up. The full server takes a free Etherscan API key, and its PRO tools need the Pro Plus\u00a0plan.<\/p>\n Etherscan\u2019s docs warn that mcp.etherscan.io is the only official server. Marketplace listings that use the Etherscan name are not from Etherscan.<\/p>\n Watch out for.<\/strong> Etherscan\u2019s tools answer one address or one transaction at a time. Ranking traders or following funds through 50 wallets means dozens of calls against your API quota. It does not cover Bitcoin, Solana or\u00a0Tron.<\/p>\n Best for:<\/strong> quick, free checks of a wallet or a transaction on Ethereum and its\u00a0rollups.<\/p>\n CoinGecko<\/a> runs a free public server that needs no API key and shares its rate limits across users. A Pro endpoint gives higher limits and the full tool set. The server exposes two tools: one searches CoinGecko\u2019s SDK docs, and one runs code against more than 100 API methods. Together they cover live and historical prices, market caps, volumes, exchange data, trending coins and DEX\u00a0pools.<\/p>\n Watch out for.<\/strong> CoinGecko returns market data only. It can tell you a token\u2019s price and where it trades. It cannot tell you who holds the token or where the funds\u00a0went.<\/p>\n Best for:<\/strong> price checks, portfolio maths and market overviews.<\/p>\n Alchemy\u2019s hosted server<\/a> signs you in with your Alchemy account, with no key and no install. Alchemy lists 168 tools across 100+ chains, split into 8 admin, 132 RPC and 28 data tools. The RPC tools cover transaction simulation, debug traces, account abstraction and Solana. The data tools cover NFTs, prices and portfolios.<\/p>\n Alchemy\u2019s free plan covers 30 million compute units per month. The company has retired its old local server. The npm package stopped working on 30 September 2026, so older setup guides no longer\u00a0apply.<\/p>\n Watch out for.<\/strong> Most tools are node calls that return raw blockchain data. A developer testing a contract wants exactly that. An analyst needs many calls to build one\u00a0answer.<\/p>\n Best for:<\/strong> developers who want their coding AI to query and simulate on-chain\u00a0state.<\/p>\n Blockscout<\/a> hosts its own server and publishes the code on GitHub under its own licence, which limits commercial use. Its 16 tools cover addresses, tokens, NFTs, contracts, transactions and blocks on more than 100 chains. It splits long responses into pages, so a busy wallet\u2019s history does not overflow the assistant\u2019s context.<\/p>\n You need a Blockscout PRO API key. The free tier gives 100,000 credits per day, and a shared fallback key works with tighter rate\u00a0limits.<\/p>\n Watch out for.<\/strong> Like Etherscan, Blockscout serves explorer data, one address or one transaction at a time. It has no tools for tracing funds or ranking\u00a0traders.<\/p>\n Best for:<\/strong> wallet and contract lookups on chains that Etherscan does not\u00a0cover.<\/p>\n altFINS MCP<\/a> is built for technical analysis: screeners, 150+ indicators and trade signals on more than 2,000 coins. It reads charts, not\u00a0wallets.Tatum\u2019s Blockchain MCP<\/a> offers 13 tools for balances, transaction history and NFT data across 130+ networks. It needs a Tatum API key and returns raw data rather than analysis.<\/p>\n Match the server to the question you ask\u00a0most:<\/p>\n \u201cWhere did this money go, and who received it?\u201d Bitquery.\u201cIs this wallet risky?\u201d Bitquery\u2019s risk\u00a0screen.\u201cCan you chart this custom metric?\u201d\u00a0Dune.\u201cWhat are big funds buying?\u201d\u00a0Nansen.\u201cWhat\u2019s in this wallet?\u201d Etherscan or Blockscout.\u201cWhat\u2019s the price?\u201d CoinGecko.\u201cHelp me build and test my app.\u201d\u00a0Alchemy.<\/p>\n You can connect more than one. Claude and Cursor both accept several servers at once, and the AI picks the tool that fits each question.<\/p>\n In Claude, open Customize \u2192 Connectors<\/strong>, click + Add<\/strong> and choose Add custom connector<\/strong>.Name it Bitquery, paste https:\/\/mcp.bitquery.io as the server URL and click\u00a0Add<\/strong>.Ask a question. The first time a Bitquery tool runs, Claude opens a sign-in page. Log in with your Bitquery\u00a0account.<\/p>\n On Claude Team and Enterprise plans, an owner adds the connector first under Organization settings \u2192 Connectors<\/strong>.<\/p>\n ChatGPT, Cursor, VS Code and Windsurf take the same URL in their connector or server settings. Bitquery\u2019s setup docs<\/a> have the steps for each\u00a0client.<\/p>\n Ask for the receipts.<\/strong> Have the assistant list the transaction hashes behind its answer, then open one in a block explorer.Check the data delay.<\/strong> Every index trails the chain. In my test, Bitquery\u2019s Polymarket data ran 17 minutes behind, and the answer said\u00a0so.Read labels as evidence.<\/strong> A label says an address was attributed to an exchange or a scam. Check the evidence before you accuse\u00a0anyone.Watch your credits.<\/strong> Every server here meters its calls, and a long investigation can make hundreds of\u00a0them.<\/p>\n What is the best MCP server for crypto analysis?<\/strong> Which crypto MCP servers work with ChatGPT and Claude?<\/strong> Is there a free crypto MCP server?<\/strong> Is there an MCP server for Polymarket?<\/strong> What is the best MCP server for Solana data?<\/strong> Is there an MCP server for Hyperliquid?<\/strong> Which MCP server is best for Bitcoin analysis?<\/strong> Can these servers trade for me?<\/strong> If your question is about prices, CoinGecko is enough.

Before you trust the\u00a0answer<\/h4>\n
FAQ<\/h4>\n
Bitquery, when the question is about who traded a token and where the money moved. It covers DEX trades on 10 chains and fund tracing on 19. For prices alone, CoinGecko\u2019s free server is\u00a0enough.<\/p>\n
All seven are hosted servers, so any client that accepts a remote server URL can try them, though sign-in support varies by client. Bitquery and Dune both name Claude and ChatGPT in their\u00a0docs.<\/p>\n
Yes. CoinGecko\u2019s public server and Etherscan\u2019s keyless server need no account at all. Blockscout and Alchemy have free plans, and Bitquery offers a 7-day trial with 100\u00a0credits.<\/p>\n
Yes. Bitquery has 14 Polymarket tools for market odds, trades, top traders and outcome holders; see the Polymarket MCP guide<\/a>. Nansen\u2019s full tool set also covers prediction markets.<\/p>\n
Bitquery covers Solana DEX trades, new token launches and fund tracing; see the Solana MCP guide<\/a>. Dune also holds Solana tables if you would rather write\u00a0SQL.<\/p>\n
Yes. Bitquery has 18 Hyperliquid tools for prices, funding rates, liquidations and trader positions; see the Hyperliquid MCP\u00a0guide<\/a>.<\/p>\n
Bitquery. It traces Bitcoin transfers and groups addresses that are likely controlled by the same owner, and does the same for Litecoin, Dogecoin, Bitcoin Cash and Dash. Dune also holds Bitcoin tables if you would rather write\u00a0SQL.<\/p>\n
This list covers servers for reading blockchain data. Bitquery is read-only, so it cannot move funds. Servers that place trades or sign transactions are a separate category.<\/p>\n
