Overview

AI-generated overview

Remote MCP endpoint for cross-chain DeFi: Solana and EVM RPC reads, AMM quotes and swaps, bridging, token launching, and AI chat.

What you can do
Read Solana state: balances, accounts, token accounts, transactions, blockhashes, signatures and slots, plus any raw Solana JSON-RPC method and a federated call to other MCP servers. Read EVM chains: any JSON-RPC method across listed networks, program discovery and introspection, ABI reconstruction from bytecode, and token/NFT search. Quote and build AMM swaps and transfers, and list or inspect AeX402 pools, including the Robinhood Chain AMM. Bridge assets across chains via LI.FI, track bridge status, and query Hyperliquid order-book and position data. Launch memecoins on the aeX402 launchpad, run AI chat through the AI Router, and delegate subtasks to specialist agent sessions. Run bounded,
When to use it
Use it when an assistant needs on-chain data or DeFi actions across Solana and several EVM chains from one endpoint: portfolio and pool inspection, swap or bridge preparation, contract introspection, or token discovery. Less suitable if you only need one chain's basic RPC, which a dedicated server may cover more simply.
Requirements
Remote streamable HTTP endpoint; nothing to install locally. No authentication or headers are declared, but paid features use x402 micropayments, so a funded wallet and the documented top-up, session-token and API-key flow are needed for anything beyond the free AI tier. Network access to the endpoint and the chains it queries.
Before you install
Some tools write to chain: sending signed transactions, building swaps and transfers, launching tokens, and bridging assets, which can move real funds. The default token launch is described as custodial, so identity and control of the launched token may sit with the service. Paid features deduct credits or require x402 payments in crypto; check prices and merchant addresses before paying. Free AI chat is limited to a few calls per day.

Installation

In SourceWeft

  1. Open aeX402 — Cross-Chain DeFi MCP: LINQ, AMM, Bridge, AI in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.aex402%2Frpc/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

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.

ParametersminTvl

Parametersaddressrequired

aex402_quote

Get a swap quote from an AeX402 pool. Calculates expected output, price impact, and fees without executing.

ParameterspoolrequiredamountrequiredinputMintrequired

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 enumerates them live by scanning VPoolGraduated events + reading each pool's reserves, so it tracks reality as coins graduate. Returns graduatedPools[] (poolId, token, reserves, TVL), graduatedPoolCount, and status ("live" | "no-graduated-pools" | "unknown"), plus the legacy standalone 0xA1F6 USDG/WETH pool (legacy-drained). Distinct from the chain's Uniswap-fork DEX. No inputs.

Takes no parameters.

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 (+ optional description/image/links). DEFAULT (custodial): the aeX402 backend SIGNS + SUBMITS the createVPool tx for you, so a claude.ai user with NO WALLET can launch in one call; returns {ok,status,txHash,vpId}. Optionally pass `creator` (a 0x address) to record as the coin owner. Pass build:true instead to get an UNSIGNED tx {to,value,data} to submit yourself (non-custodial — that requires `creator` and makes you the on-chain creator). A custodial call SIMULATES first, so a failure burns no gas: status "gated" means createVPool reverts in simulation (cause not determined — likeliest are the ticker still being claimed by a bonding coin or this vpId being taken; see `detail`/`revertData`), and status "unreachable" means the chain could not be reached, which is retryable. The launchpad is NOT chain-gated: createVPool simulates clean from an arbitrary sender (measured 2026-09-25).

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 (rpc.slonana.com), which additionally exposes RPC methods no other network has: getAlpenglowHealth (consensus migration status), getBridgeStatus, getAexchanRelays, getValidatorStats, quote. (listSvmNetworks/enableSvmNetwork/disableSvmNetwork/setNetworkRpcUrl also exist but are inert API-compat stubs — listSvmNetworks always reports one hardcoded network and the enable/disable/set calls ignore their arguments and return true; verified in source, not live network-management controls.) For tools that exist ONLY on Slonana's MCP server with no RPC-method equivalent (the aea_* agent registry), use mcp_call instead.

Parametersmethodrequiredparamsnetwork

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 that server's tools/list first if you don't know its tool names.

Parameterstoolserverrequiredarguments

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 (988), plasma (9745), tempo (4217), codex (81224), arc (5042, Circle mainnet).

Parametersmethodrequiredparamsnetwork

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(...).take(...), JSON pipeline steps, or reducers. Use mcp_linq when you want one aggregate answer instead of N tool calls.

ParameterslinqcallsrequiredreducepipelineconcurrencyignoreFailures

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 unsigned transactionRequest (to/data/value/gasLimit) that the CALLER signs and submits on the fromChain — no keys are held here. Chains by id or key (1 Ethereum, 42161 Arbitrum, 8453 Base, 10 Optimism, 137 Polygon, 999 HyperEVM, 4663 Robinhood Chain). Tokens by symbol or 0x address.

ParameterstoChainrequiredtoTokenrequiredfromChainrequiredfromTokenrequiredtoAddressfromAmountrequiredfromAddressrequired

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).

ParametersbridgetxHashrequiredtoChainfromChain

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 user's positions/margin), spotMeta, meta+assetCtxs (mark/funding/OI), candleSnapshot, and more. For type:metaAndAssetCtxs specifically: the raw response is TWO PARALLEL top-level arrays (universe names, asset contexts) correlated only by array position — do not try to read/scan it directly for '200+ coins' style questions (funding-rate outliers, biggest open interest, highest volume). Pass rankBy instead: it joins the two arrays server-side, sorts, and returns only the top N — the correct way to answer 'what has the highest/most extreme funding/OI/volume right now'.

ParametersdircointyperequireduserlimitrankByendTimeintervalstartTime

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, /ai/stats, /leaderboard, /openapi.json, /llms.txt, /rh/pools (Robinhood), /hl/pools (HyperEVM), /base/pools (Base Uniswap v3), /eth/pools (Ethereum Uniswap v3), /arb/pools (Arbitrum Uniswap v3)

Parameterspathrequired

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 recent block activity (refreshed hourly) — each carries an `activity` count of recent invocations/calls; entries with type "discovered" were seen live on-chain but not yet named. Use this to learn what is actually active on-chain right now, then describe_program to introspect any specific address.

Parameterschain

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 proxy → implementation) PLUS Blockscout explorer enrichment when available.

Parameterschainrequiredaddressrequired

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 signature DBs (openchain/4byte) know to human signatures. Works on UNVERIFIED contracts because bytecode is ground truth, but it is NOT a full ABI: novel/proprietary selectors DBs have never seen stay unresolved (decompile for those). Use it to understand what an unknown contract does before trusting behavior-based guesses.

Parameterschainrequiredaddressrequired

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 — live spot price + 24h volume. The census is refreshed hourly (canonical tokens from Hyperliquid spotMeta, top tokens from Blockscout, spam-filtered). Use this instead of discover_programs when you want a specific asset (e.g. "USDC on hyperevm", "stablecoins on robinhood") rather than the whole list.

Parameterschainlimitquery

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 / search_tokens data is current before relying on it.

Takes no parameters.

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 addresses, step-by-step topup → session-token → API-key flow, and how to attach credentials to MCP calls. This tool is FREE and NEVER rate-limited — call it when you hit a 402 / rate limit to convert into a paid session ($0.01 minimum buys 100 calls, no signup).

Takes no parameters.

fetch

Fetch the full document for one search result id (from the search tool). Accepts token:<chain>:<address>, program:<chain>:<address>, or pool:<address>. Returns the entity detail (on-chain state for pools, census entry for tokens, registry/introspection for programs) as a document.
