  What this check looks for
Description, as the server wrote it
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).
solana_buildTransferBuild a SOL or SPL token transfer instruction.No findings
Why it is in this group
- The name "solana_buildTransfer" says "transfer": a word for a change that another call does not undo.
- The input addresses people (input.to): what it sends cannot be taken back.
Description, as the server wrote it
Build a SOL or SPL token transfer instruction. Returns instruction JSON (programId, keys, data) for client-side TX construction and signing.
solana_sendTransactionSubmit a signed transaction to the network.No findings
Why it is in this group
- The name "solana_sendTransaction" says "send": a word for sending, and what is sent cannot be taken back.

aex402_buildSwapBuild an AeX402 AMM swap action.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
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.
agent_delegateDelegate a task to an independent specialist AI agent session.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
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.

Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
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.
discover_programsDiscover on-chain programs/contracts across every chain this RPC supports (Solana, Slonana SVM, Robinhood, HyperEVM, Ethereum, Base, Stable, Plasma, Tempo, Codex).No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
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.

Description, as the server wrote it
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.
evm_rpcCall ANY EVM JSON-RPC method on a supported chain — eth_getBalance, eth_call, eth_blockNumber, eth_sendRawTransaction, eth_getLogs, ...No findings
Why it is in this group
- The description's first verb is "call": a word for a change.
Description, as the server wrote it
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).

Why it is in this group

Description, as the server wrote it
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).

  description: "Call a tool on another MCP server this RPC federates with, for tools that..."
  What this check looks for
Description, as the server wrote it
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.
mcp_linqPrimary LINQ-style MCP workflow tool.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
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.
reconstruct_abiReconstruct a PARTIAL function/event interface for an EVM contract on a supported EVM chain from its BYTECODE — no source or verification needed.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
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.
solana_rpcCall ANY Solana-compatible JSON-RPC method by name — full RPC surface beyond the typed solana_* tools (getProgramAccounts, getBlock, getEpochInfo, simulateTransaction, ...).No findings
Why it is in this group
- The description's first verb is "call": a word for a change.
Description, as the server wrote it
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.

  What this check looks for
Description, as the server wrote it
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.
aex402_quoteGet a swap quote from an AeX402 pool.No findings
Why it is in this group
- The description's first verb is "get": a word for reading.
Description, as the server wrote it

aex402_rh_poolGet the live state of the aeX402 AMM on Robinhood Chain (EVM 4663) — the diamond-contract port of the Solana AMM.No findings
Why it is in this group
- The description's first verb is "get": a word for reading.
Description, as the server wrote it
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.

bridge_statusTrack a cross-chain bridge submitted via bridge_quote — returns DONE / PENDING / FAILED plus the receiving-chain tx once it completes.No findings
Why it is in this group
- The name "bridge_status" says "status": a word for reading.
Description, as the server wrote it
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).
describe_programIntrospect ANY specific program/contract address on a chain.No findings
Why it is in this group
- The name "describe_program" says "describe": a word for reading.
Description, as the server wrote it
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.
fetchFetch the full document for one search result id (from the search tool).No findings
Why it is in this group
- The name "fetch" says "fetch": a word for reading.
Description, as the server wrote it
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.
hl_infoQuery the Hyperliquid Info API — the perps/spot order-book data layer (read-only, no auth).No findings
Why it is in this group
- The description's first verb is "query": a word for reading.
Description, as the server wrote it
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'.
searchSearch the aeX402 universe by keyword: tokens (Robinhood Chain + HyperEVM census), known programs/contracts (Solana, Robinhood, HyperEVM, Slonana), and live AeX402 AMM pools.No findings
Why it is in this group
- The name "search" says "search": a word for reading.
Description, as the server wrote it
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 full detail. Use the specialist tools (search_tokens, discover_programs, aex402_listPools) when you already know the entity type.
search_tokensSearch the live token/NFT census for Robinhood Chain (4663) and HyperEVM (999) by symbol or name.No findings
Why it is in this group
- The name "search_tokens" says "search": a word for reading.
Description, as the server wrote it
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.
solana_getAccountInfoGet raw account info (owner, lamports, data) for any Solana address.No findings
Why it is in this group
- The name "solana_getAccountInfo" says "get": a word for reading.
Description, as the server wrote it
