Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 33 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability69
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 5511 tokens (~167/item across 33 items; 33 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (82% of tools); any adoption earns full credit.Pass
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 3 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "solana_sendTransaction" implies "send" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 34 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities40
- Spec-recency check failed: implements MCP spec 2025-03-26; the latest is 2026-07-28. See how to fix → Fail
How do I install the aeX402 — Cross-Chain DeFi MCP: LINQ, AMM, Bridge, AI server?
aeX402 — Cross-Chain DeFi MCP: LINQ, AMM, Bridge, AI is a hosted endpoint at https://rpc.aex402.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

hl_info ~526
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'.
| Name | Type | Req | Description |
|---|---|---|---|
| coin | string | – | Coin symbol for l2Book/candleSnapshot (e.g. BTC, ETH) |

| rankBy | string | – | type:metaAndAssetCtxs ONLY. One of funding | fundingAbs | openInterest | volume. Joins each coin's name to its funding/OI/volume, drops delisted coins, sorts, and returns {ranked, rankBy, dir, totalC… |
| startTime | number | – | candleSnapshot only: start time epoch ms (default: endTime minus 500 intervals) |
| type | string | yes | Info request type, e.g. meta, l2Book, allMids, clearinghouseState, metaAndAssetCtxs |
| user | string | – | 0x address for user-scoped queries (clearinghouseState, openOrders, userFills) |

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). Live create is gated on the launchpad facet upgrade (pending); until enabled a custodial call returns status "gated" and burns no gas.
| Name | Type | Req | Description |
|---|---|---|---|
| build | boolean | – | If true, return an UNSIGNED tx to submit yourself (non-custodial) instead of the backend launching for you. Default false. |
| creator | string | – | OPTIONAL 0x EVM address recorded as the coin owner (and seeds the vpId). REQUIRED only when build:true (then it is the self-signing on-chain creator). |
| description | string | – | Short description (<=256 chars) — off-chain metadata |
| image | string | – | Image URL (https:// or ipfs:// only) — off-chain metadata |
| links | array | – | Up to 3 links (https:// or ipfs:// only) — off-chain metadata |
| name | string | yes | Token name, 1..32 bytes (e.g. "Fork Meme") |
| pad | string | – | OPTIONAL aeX402 launchpad slug the coin is launched on. Its vpId then starts with that pad's tag, so the pad lists it. build:true only |
| ticker | string | yes | Ticker / symbol, 1..16 bytes (e.g. "FMEME") |
| Name | Type | Req | Description |
|---|---|---|---|
| data | string | – | build mode: createVPool calldata to submit |
| metadata | object | – | Off-chain metadata (stored server-side in custodial mode) |
| note | string | – | – |
| ok | boolean | – | Custodial mode: whether the launch was submitted |
| status | string | – | submitted | gated | custodial-disabled | exists | rate-limited | insufficient-gas | submit-failed |
| to | string | – | build mode: aeX402 diamond address |

mcp_call ~152
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.
| Name | Type | Req | Description |
|---|---|---|---|
| arguments | object | – | Arguments for the tool call, per that server's own schema. |
| server | string | yes | Federated server name. One of: slonana |

No examples provided.
mcp_linq ~797
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.
| Name | Type | Req | Description |
|---|---|---|---|
| calls | array | yes | Read-only MCP tool calls to run. Each call has {id?, tool, args?, pick?}. pick is a dot path into that call output; [] flattens arrays. |
| concurrency | number | – | Parallelism for subcalls (default 8, max 12). |
| ignoreFailures | boolean | – | When reduce/pipeline/linq is used, a failed subcall is normally still reported in `failures` alongside the aggregate result, since a `.where(ok)`-style query would otherwise make it invisible. Set tr… |
| linq | string | – | LINQ-like query string compiled into pipeline steps. Supports fluent dot chaining and query clauses. .where()/.map()/.select() bodies AND .orderBy()/.orderByDesc()/.distinctBy()/.groupBy() keys are a… |
| pipeline | array | – | LINQ-style chained transforms over the raw batch result. Each step feeds the next. Ops: from, expand, where, select/project, groupBy, orderBy/sort, take/limit, skip, distinct, count, sum, avg, min, m… |
| reduce | object | – | Named reductions to compute from subcall outputs. Example: {"total":{"op":"sum","path":"results[].picked"},"top":{"op":"top","path":"results[]","sortBy":"picked","limit":5}}. |
| Name | Type | Req | Description |
|---|---|---|---|
| calls | integer | – | number of subcalls attempted; omitted when reduce/pipeline/linq was requested |
| concurrency | integer | – | omitted when reduce/pipeline/linq was requested |
| failures | array | – | omitted when every subcall succeeded, when ignoreFailures:true was passed, or when no aggregation was requested (failures show inside results instead) |
| note | string | – | omitted when reduce/pipeline/linq was requested |
| ok | boolean | – | omitted when reduce/pipeline/linq was requested — the aggregation response is just the answer, not this batch-fanout shape |
| reductions | object | – | named reducer outputs; omitted when args.reduce was not passed |
| result | – | – | The pipeline/linq output value — the entire point of the call when args.pipeline or args.linq was passed, returned alone rather than wrapped; omitted when neither was passed |
| results | array | – | omitted when reduce/pipeline/linq was requested — see failures instead for what went wrong |

payment_help ~137
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).

| quickstart | object | – | – |
No examples provided.
reconstruct_abi ~177
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.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | EVM contract address (0x…). For a proxy, pass the implementation for the real logic. |
| chain | string | yes | robinhood | hyperevm | ethereum | base | stable | plasma | tempo | codex |

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.

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.
