chain 4663 data server: free, zero-config trading server: opt-in, spend-capped

MCP servers for Robinhood Chain

Stock Token quotes, multiplier-correct portfolios, memecoin launches, and chain stats — free and read-only. Plus a separate, explicitly opt-in trading server with hard spend caps and a confirm gate for agents that want to act, not just look.

A real session

This is an unedited MCP tool call against the live server in this repo, captured against Robinhood Chain mainnet during the build — the same stdio transport Claude Code, Claude Desktop, and Cursor use.

What's GME trading at on Robinhood Chain, and what's the premium over the oracle price?

→ calling get_stock_quote({ "symbol": "GME" })

{
  "symbol": "GME",
  "name": "GameStop • Robinhood Token",
  "chainlink": { "priceUsd": 21.76125, "ageSeconds": 169330 },
  "dexPriceUsd": 20.521686,
  "premiumPct": -5.6962,
  "premiumNote": "positive = DEX trades above oracle",
  "uiMultiplier": "1000000000000000000",
  "underlyingSharePriceUsd": 21.76125,
  "sources": ["chainlink", "uniswap-v3", "robinhood-chain-rpc"]
}

The Chainlink oracle prices the GME Stock Token at $21.76. It's actually trading at $20.52 on the token's Uniswap v3 pool — a 5.70% discount to the oracle. The uiMultiplier is 1e18 (1:1), so that's also the underlying share price: no split or reinvested-dividend adjustment has happened yet.

Two servers

One package, two binaries, two very different trust levels.

hood-mcp free

9 read-only tools. No API key, no wallet, no config — runs against the public RPC out of the box. Stock Token quotes with live oracle + DEX premium, multiplier-correct portfolios, memecoin data, launch scanning, chain stats.

hood-mcp-trading opt-in

4 tools for one configured wallet. Refuses to start without an explicit kill switch. Every mutating call is spend-capped in USD and requires a second, confirmed call to broadcast. See the safety model.

Why this exists

Robinhood Chain launched 2026-07-01. As of this build, the ecosystem has exactly two other MCP servers for the chain — both zero-star, read-only hobby projects a few days old. This is the productized one: a full data surface plus a trading surface built to a real safety bar, not a demo.

Multiplier-correct

Stock Tokens implement ERC-8056. Raw balances understate positions after a split or reinvested dividend — this server does the share math right, same as the underlying hoodchain SDK.

Real upstreams

Chainlink, Uniswap v3, Blockscout, GeckoTerminal, DefiLlama — no cached fixtures, no placeholder data. Every tool call hits the chain or a real API.

Guarded by default

The trading server ships with spend caps and a confirm gate on by default. An agent cannot move funds on the first call, ever.
