hoodsynapse-mcp

An MCP server that gives AI agents read access to Robinhood Chain — live blocks, tokenized real-world assets, memecoins, and the history an RPC can't return.

No key. No account. Everything it reports is verifiable against the chain.

Why

Agents that touch a chain need data they can trust. Robinhood Chain carries tokenized equities (NVIDIA, Tesla, Apple), ETFs (S&P 500, silver), private companies (SpaceX) and native memecoins — but a raw RPC answers only for the present, in hex.

This server hands an agent the clean version, plus the history.

Install

Add it to your MCP client config:

{
  "mcpServers": {
    "hoodsynapse": {
      "command": "npx",
      "args": ["-y", "hoodsynapse-mcp"]
    }
  }
}

For Claude Desktop that file is:

• macOS — ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows — %APPDATA%\Claude\claude_desktop_config.json

Restart the client and the tools appear.

Tools

| Tool | What the agent gets | | --- | --- | | get_chain_stats | Latest block, block time, gas, L1 anchor | | list_tokens | Tokens by activity — filter rwa, equity, fund, private, stable, native | | get_block | One block, Orbit fields decoded, system txs separated | | get_daily_activity | Daily transactions and block cadence, drawn as a chart | | get_index_status | What the index holds and how far behind the chain it is | | get_gas | Gas price, base fee, and why priority fees are zero here |

What an agent can answer with this

• "What real-world assets trade on Robinhood Chain?" → NVIDIA, GameStop, Alphabet, SpaceX, iShares Silver, Strategy, Apple, Tesla, S&P 500 …
• "How busy is the chain today versus last week?"
• "What's block 20,401,056 and how much gas did it burn?"
• "Is the index current enough to trust this answer?"

Sample output from list_tokens({ kind: "rwa" }):

RWA tokens on Robinhood Chain, by activity

 1. NVDA       equity      1,555 transfers   NVIDIA • Robinhood Token
 2. GME        equity      1,484 transfers   GameStop • Robinhood Token
 3. GOOGL      equity        752 transfers   Alphabet Class A • Robinhood Token
 4. SPCX       private       749 transfers   Space Exploration Technologies Corp.
 5. SLV        fund          560 transfers   iShares Silver Trust • Robinhood Token

How the data gets there

Live values (get_chain_stats, get_block, get_gas) come straight from the chain's public RPC. History (get_daily_activity, list_tokens) comes from the Hood Synapse index — a database that samples the chain continuously, because Robinhood Chain produces around 10 blocks per second and an RPC keeps no past.

get_index_status always reports the index's real coverage, so an agent can tell the difference between "no activity" and "not indexed yet".
