aeX402 — Cross-Chain DeFi MCP: LINQ, AMM, Bridge, AI is an MCP server with 33 tools an agent can call, among them aex402_buildSwap, aex402_getPool, aex402_listPools. It answers at https://rpc.aex402.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 4 September 2026; the last check, on 17 October 2026, succeeded.
Agent MCP for DeFi: cross-chain LINQ fan-out, AMM quotes/swaps, bridge, AI. Solana+EVM. Free+x402.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
aex402_buildSwap | Build an AeX402 AMM swap action. Fetches live pool state, computes output with slippage protection, returns all instruction parameters and account addresses for client signing. Inputs: pool, inputMint, amount, slippageBps, userWallet |
aex402_getPool | Get detailed AeX402 pool info: token mints, balances, fee, amplification, LP supply, analytics (OHLCV candles), circuit breaker status. Inputs: address |
aex402_listPools | List all AeX402 AMM pools on Solana. Returns pool addresses with basic info (mints, balances, fee, amp). Pools are 1024-byte accounts owned by program 3AMM53MsJZy2Jvf7PeHHga3bsGjWV4TSaYz29WUtcdje. Inputs: minTvl |
aex402_quote | Get a swap quote from an AeX402 pool. Calculates expected output, price impact, and fees without executing. Inputs: pool, inputMint, amount |
aex402_rh_pool | Get the live state of the aeX402 AMM on Robinhood Chain (EVM 4663) — the diamond-contract port of the Solana AMM. The AMM is the set of GRADUATED launchpad coins whose pools are seeded in-diamond on the canonical launchpad (0xED2F); this en |
agent_delegate | Delegate a task to an independent specialist AI agent session. The delegate runs with full tool access and returns its response. Useful for breaking complex tasks into subtasks. Max depth: 3. Inputs: session, role, message, model |
ai_chat | Send a chat completion request to the aeX402 AI Router. Free tier: 3 calls/day. Paid: deducts credits based on token usage. Inputs: model, messages, max_tokens, temperature, reasoning_effort |
api_get | GET any public read endpoint of rpc.aex402.com: /health, /credits?wallet=, /pumpfun?limit=, /pumpfun/tuple?mint=, /security/<pool>, /market/list, /sniper/leaderboard, /sniper/bets?id=, /settlement/<sig>, /settlements/<wallet>, /ai/models, / Inputs: path |
bridge_quote | Bridge/swap ANY asset across ANY chain via LI.FI (the engine behind Jumper) — e.g. Arbitrum USDC → Robinhood Chain (4663) USDG, or bridge into ETH for gas. Returns the best route (estimated output, fees, bridge used, duration) PLUS an unsig Inputs: fromChain, toChain, fromToken, toToken, fromAmount, fromAddress |
bridge_status | Track a cross-chain bridge submitted via bridge_quote — returns DONE / PENDING / FAILED plus the receiving-chain tx once it completes. Pass the source-chain tx hash (and the bridge tool from the quote for a faster lookup). Inputs: txHash, bridge, fromChain, toChain |
describe_program | Introspect ANY specific program/contract address on a chain. Solana/Slonana: returns executable, owner, data size, and whether it is a known program. EVM: RPC-verified facts (is-contract, code size, ERC-20 name/symbol/decimals, EIP-1967 pro Inputs: chain, address |
discover_programs | Discover on-chain programs/contracts across every chain this RPC supports (Solana, Slonana SVM, Robinhood, HyperEVM, Ethereum, Base, Stable, Plasma, Tempo, Codex). Returns a curated seed MERGED with programs/contracts AUTO-DISCOVERED from r Inputs: chain |
discovery_health | Report the freshness and health of the cross-chain program/token discovery pipeline: when the hourly cron last ran, how many programs/tokens each chain scan produced, and which scans failed. Use this to check whether discover_programs / sea |
evm_rpc | Call ANY EVM JSON-RPC method on a supported chain — eth_getBalance, eth_call, eth_blockNumber, eth_sendRawTransaction, eth_getLogs, ... Chains: robinhood (4663) / robinhood-testnet (46630), hyperevm (999), ethereum (1), base (8453), stable Inputs: method, params, network |

hl_info | Query the Hyperliquid Info API — the perps/spot order-book data layer (read-only, no auth). The 'type' field selects the query: meta (perps universe + leverage), l2Book (order book for a coin), allMids (mid prices), clearinghouseState (a us Inputs: type, coin, user, rankBy, limit, dir |
launch_token | Launch a memecoin on the aeX402 launchpad on Robinhood Chain (EVM 4663) for a FIXED pump.fun-style bonding curve (1B supply, starts 0.0001 USDG, graduates at 10,000 USDG raised, quoted in USDG). You supply only identity — name + ticker (+ o Inputs: name, ticker, creator, description, image, links |
mcp_call | Call a tool on another MCP server this RPC federates with, for tools that have no equivalent in solana_rpc/evm_rpc (no underlying JSON-RPC method — e.g. Slonana's aea_list_services/aea_resolve agent registry). Known servers: slonana. Call t Inputs: server, tool, arguments |
mcp_linq | Primary LINQ-style MCP workflow tool. Run one bounded MCP call: fan out up to 32 READ-ONLY tool calls across chains, then compose the combined result with fluent chains like results.selectMany(...).where(...).groupBy(...).orderByDesc(...).t Inputs: calls, reduce, pipeline, linq, concurrency, ignoreFailures |
payment_help | How to pay for API access (x402 micropayments) — the complete self-serve guide for agents: current prices, every accepted asset/chain (USDC/USDT/SOL/ANSEM on Solana, ETH/USDG on Robinhood Chain, USDC/HYPE on HyperEVM), the merchant addresse |
reconstruct_abi | Reconstruct a PARTIAL function/event interface for an EVM contract on a supported EVM chain from its BYTECODE — no source or verification needed. Extracts PUSH4 function selectors + recent event topic0 hashes and resolves the ones public si Inputs: chain, address |
search | Search the aeX402 universe by keyword: tokens (Robinhood Chain + HyperEVM census), known programs/contracts (Solana, Robinhood, HyperEVM, Slonana), and live AeX402 AMM pools. Returns a result list; pass a result id to the fetch tool for ful Inputs: query |
search_tokens | Search the live token/NFT census for Robinhood Chain (4663) and HyperEVM (999) by symbol or name. Returns matching tokens with address, standard (erc20/erc721/erc1155), decimals, holders, market cap, and — for HyperEVM canonical tokens — li Inputs: query, chain, limit |
solana_buildTransfer | Build a SOL or SPL token transfer instruction. Returns instruction JSON (programId, keys, data) for client-side TX construction and signing. Inputs: from, to, amount, mint |
solana_getAccountInfo | Get raw account info (owner, lamports, data) for any Solana address. Inputs: address, encoding |
solana_getBalance | Get SOL balance for a wallet address (in lamports). Divide by 1e9 for SOL. Inputs: address |
solana_getLatestBlockhash | Get latest blockhash for transaction building. Returns blockhash + lastValidBlockHeight. |
solana_getSignaturesForAddress | Get recent transaction signatures for an address. Returns up to 20 most recent. Inputs: address, limit |
solana_getSlot | Get the current slot number. |
solana_getTokenAccountsByOwner | Get all SPL token accounts owned by a wallet. Returns mint, balance, decimals for each token. Inputs: owner |
solana_getTransaction | Get full transaction details by signature, including instructions, logs, and status. Inputs: signature |
solana_rpc | Call ANY Solana-compatible JSON-RPC method by name — full RPC surface beyond the typed solana_* tools (getProgramAccounts, getBlock, getEpochInfo, simulateTransaction, ...). Defaults to Solana mainnet; pass network:slonana to query Slonana Inputs: method, params, network |
solana_sendTransaction | Submit a signed transaction to the network. Returns transaction signature. Inputs: transaction |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://rpc.aex402.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
