A paid MCP server: market-intel tools your agent pays for per call

MCP (streamable HTTP) · x402 · USDC on Base (eip155:8453) · updated 2026-10-06

https://api.newsgurus.ai/mcp/ is a remote MCP server for the News Gurus Intel API. The July 13, 2026 guide said it exposed “the same five products as the HTTP API.” That sentence is wrong now. get_catalog lists 38 priced tools, plus one free tool, get_catalog.

Opening the MCP URL in a browser returns HTTP 406. It speaks JSON-RPC to agents, not HTML to people. The manifest is https://api.newsgurus.ai/mcp.json. The HTTP menu is larger than the MCP tool list; see the last section.

Connect

Catalog inspection is free. Paid tools challenge with HTTP 402 unless the client presents a subscriber key.

{
  "mcpServers": {
    "newsgurus-intel": {
      "type": "http",
      "url": "https://api.newsgurus.ai/mcp/"
    }
  }
}

With a standard client you can initialize, list tools, and call get_catalog. To finish a paid call, the client must either settle x402 or send a subscriber key.

The server is listed in the official MCP Registry as io.github.CollectorGuru/newsgurus-intel.

How an agent pays

Two ways. There is no request signing, no API secret, and no nonce header. The October 6, 2026 catalog says the key alone is the credential, over HTTPS, or the payment itself is the credential.

1. HTTP 402 and USDC on Base. The client calls a priced tool with no key. The server returns 402 with payment requirements. The client signs an EIP-3009 transferWithAuthorization USDC authorization. The July 13 version of this guide states this is gasless for the payer: the facilitator settles, and the client retries. Network is eip155:8453. The asset is USDC. The wallet needs USDC on Base, not ETH for gas, according to that guide. Settlement is described there as the Coinbase CDP facilitator, with the purchase auditable on Base.

2. Subscriber key. Request a subscriber key from News Gurus. Send Authorization: Bearer or X-API-Key. If the client cannot set headers, ?api_key= is the fallback the catalog documents. Inside the plan rate limit those calls are not charged as x402. A missing, invalid, or over-limit key falls through to the 402 challenge.

Pay per tool call from Python

This is the sample already on this guide. It was not re-run for this update. Replace the placeholder with your own buyer key.

pip install x402 mcp eth-account

import asyncio
from eth_account import Account
from mcp import ClientSession
from mcp.client.streamable_http import streamablehttp_client
from x402.client import x402Client
from x402.mcp import x402MCPSession
from x402.mechanisms.evm import EthAccountSigner
from x402.mechanisms.evm.exact import ExactEvmScheme

async def main():
    acct = Account.from_key("0xYOUR_BUYER_PRIVATE_KEY")
    client = x402Client()
    client.register("eip155:8453", ExactEvmScheme(signer=EthAccountSigner(acct)))

    async with streamablehttp_client("https://api.newsgurus.ai/mcp/") as (read, write, _):
        async with ClientSession(read, write) as session:
            mcp = x402MCPSession(session, client)
            await mcp.initialize()
            free = await mcp.call_tool("get_catalog", {})        # $0
            paid = await mcp.call_tool("get_market_regime", {})  # $0.002
            print(paid)

asyncio.run(main())

get_catalog is the window shop. get_market_regime is the cheapest paid check ($0.002) and returns TRENDING, MEAN_REVERTING, or VOL_EXPANSION.

The 38 priced tools

Call these names. Prices are USDC per call from get_catalog on October 6, 2026.

SharedBrain is the 40-source store behind get_recent_intel, get_narratives, get_anomalies, get_trade_decisions, and get_kelly_outcomes.

Spend order: get_agents_status or get_market_regime first ($0.002), get_signals or get_recent_intel when a symbol is in play, get_composite_signal when you want the merged count ($0.05), get_symbol_tearsheet only when a decision is close ($0.50).

Why MCP instead of raw HTTP

• Tool schemas travel with the server, so the agent learns inputs at connect time.
• One session covers discovery, payment, and calls.
• get_catalog stays free, so a new client can price the menu before it spends.
• The same economics exist as plain HTTP, documented on the agent market-data guide.

What MCP does not expose: confirm before live

• GET /api/v1/signals — $0.01
• GET /api/v1/sentiment — $0.01
• GET /api/v1/brain/{symbol} — $0.02, SharedBrain context for one symbol
• Eight GET /x402/fantasy/* routes from $1 to $3: rankings, waivers, streaming, lineup, draft-pick, trade, playoff, draft-advisor

newsgurus.ai/llms.txt still says “37+ endpoints” and describes OpenAPI as 47 paths. Those counts include surface area beyond the 38 MCP tools. Do not tell an MCP client to call a fantasy route by a get_ name unless get_catalog lists it.

Free probes, not MCP tools: /public/regime, /public/narratives, /public/catalog.
