Rigel — give your AI agent eyes on Solana

Terminal simulated demo

Is this pump.fun token a rug? 7xKq…F2ab

⚙ rigel_analyze_rug_risk · 7xKq…F2ab 0.4s
Checked — here's the shape of it:

✓ Mint authority — revoked · safe
✓ Freeze authority — none · safe
⚠ Top 10 holders — 41.2% of supply · concentrated
✓ Bonding curve — 87% complete · healthy

Authorities are clean, but the top 10 wallets hold 41% — one seller moves this hard.
MEDIUM RISK

What's in the dev's wallet?

⚙ rigel_get_wallet_balance · 3nVt…9dQx 0.3s
12.4 SOL and three tokens. The biggest bag is 34.1M of the token above — the same 41% concentration. The dev is the whale. That's your risk.

How close is it to graduating?

⚙ rigel_inspect_token_data · 7xKq…F2ab 0.2s
87.3% — the curve holds 72.4 SOL and needs ~6 more to migrate. At the current buy pace, that's under an hour. One thing to hold in your head: if the dev's 34.1M hits the book before migration, this never graduates. Watch the wallet, not the chart.

Ask the chain like you'd text a friend

Rigel is an open-source MCP server. Add it once and your agent can read Solana — no dashboards, no explorers, no tab-switching.

Works where your agent works

One MCP server, every client. Your agent picks up the tools and uses them like any other skill.

Reads everything, touches nothing

No private keys, no signing, no custody. Rigel can look at any address on the chain — it can never move a lamport.

Runs on your machine

Local stdio transport straight into your client. Queries go from your machine to your RPC — nothing in between.

From question to answer in one message

No forms, no API keys, no accounts. Your agent already knows how to do this — Rigel just gives it the chain.

Add Rigel to your agent

One block in your MCP config, or run it straight from npm.

Ask about anything on-chain

A wallet, a mint, a fresh pump.fun launch — plain language is the interface.

claude_desktop_config.json

  "mcpServers": {
    "rigel-solana": {
      "command": "npx",
      "args": ["-y", "@rigel-protocol/solana-mcp"],

No keys, ever. The only thing in the config is which RPC to read from — Rigel is read-only by design.

Questions, answered

Can it steal my keys?

It never has them. Rigel takes no private keys, no seed phrases, and has no signing code at all — the config contains only an RPC URL. It reads public chain data, nothing else.

Which agents does it work with?

Anything that speaks MCP over stdio: Claude Desktop, Claude Code, Cursor, and most agent frameworks. If your client has an mcpServers config block, it works.

Does it cost anything?

No. It's MIT-licensed open source, and reading the chain is free. If you hammer it hard you may want a free API key from an RPC provider like Helius — set it via SOLANA_RPC_URL.

Is the rug-risk score financial advice?

No. It's a report of on-chain facts — authority status, holder concentration, curve state. What you do with those facts is entirely yours. A "low risk" reading is not a recommendation to buy anything.

Where does the data come from?

Directly from the Solana RPC you configure, plus pump.fun on-chain program accounts for bonding-curve tokens. No third-party API sits between your agent and the chain.
