Transport: Streamable HTTP
Category: Other

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on the maker’s server: what you ask it goes through their server.
The registry lists no key to fill in.

You need

Common questions

Is Cortexcloud safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.5.0) reached the registry 14 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

@cortexcloud.org/mcp

MCP server for CortexCloud — pay-per-call on-chain data and intelligence for AI agents. Token, wallet, risk, whale, balance, NFT, transaction and cross-chain reads, settled in USDC on Base over x402. No API keys, no subscriptions, no signup.

Two ways to connect

1. Remote (recommended). The hosted server speaks Streamable HTTP and is always current:

"mcpServers": { "cortexcloud": { "type": "http", "url": "https://api.cortexcloud.org/mcp" } } }

2. stdio bridge. This package, for clients that can only launch a local process:

"mcpServers": { "cortexcloud": { "command": "npx", "args": ["-y", "@cortexcloud.org/mcp"] } } }

The bridge is a transport adapter, not a second implementation: it forwards tools/list and tools/call to the hosted server, so tools, schemas and prices can never drift from the API.

Tools

17 tools, served from the live registry:

Paid (15) — cortex_token_intel ($0.030), cortex_cross_chain_compare ($0.040), cortex_whale_alerts ($0.030), cortex_token_risk ($0.020), cortex_wallet_intel ($0.006), and the $0.004 data routes: cortex_token_price, cortex_token_balances, cortex_nft_ownership, cortex_tx_history, cortex_gas_oracle, cortex_block, plus the batch tools cortex_aggregate_balances, cortex_aggregate_nfts, cortex_aggregate_prices, cortex_aggregate_tx_history (up to 20 items per call).
Free (2) — cortex_capabilities (every route, chain and price) and cortex_prices (the price table).

The authoritative list is always GET https://api.cortexcloud.org/v1/capabilities, or cortex_capabilities over MCP.

How payment works

A paid tool call without payment returns the x402 challenge inside the tool result: price, payee, asset, network, and the endpoint to call. Nothing is charged and no wallet is needed to read it.

To settle, the caller signs an EIP-3009 USDC authorization and replays the request with the payment-signature header. Over MCP the server relays that header to the API unchanged; it holds no funds and never signs. Over stdio, forward an existing signature with:

CORTEXCLOUD_PAYMENT_SIGNATURE=<base64 header> npx -y @cortexcloud.org/mcp

For a complete paid flow from code, use the REST reference client — 402 -> sign -> 200 in one file:

https://api.cortexcloud.org/examples/paid_client.py

Env

Variable	Default	Meaning
`CORTEXCLOUD_BASE`	`https://api.cortexcloud.org`	API base; the bridge connects to `/mcp`
`CORTEXCLOUD_PAYMENT_SIGNATURE`	—	Optional x402 payment header forwarded on every call

Verified behaviour

initialize advertises protocol 2025-06-18; the upstream server reports version 0.5.0.
tools/list returns 17 tools.
cortex_capabilities returns the live catalog with no payment.
cortex_token_price without payment returns the 402 challenge, not an error.
