# Try Solscan MCP for Free: Introducing the Public MCP Server

AI agents are getting good at answering questions about Solana, as long as they can reach real on-chain data. Solscan MCP was built for exactly that: a standard interface that connects Claude, Codex, and other MCP-compatible agents to live, decoded Solana data.

Until now, using it meant a Pro plan. Today we're opening it up with the **Solscan Public MCP server**: a free way to connect your agent to Solscan, using nothing but a free Level 1 API key. No paid plan and no credit card. Just register a Solscan account and you're in.

### What you get

**Free network & analytics tools.** These cover the network overview and daily, network-wide analytics, and they're fully usable on a Level 1 key.

Tool

Returns

Chain Info

Solana network overview: block height, epoch, slot, transaction count

Transaction Analytics

Daily transactions: total / vote / non-vote

Compute Units Analytics

Daily compute units consumed

Stake Analytics

Daily active stake (SOL + USD)

Fees Analytics

Daily transaction fees: base + priority (SOL + USD)

Slots Analytics

Blocks / slots produced per day

DEX Activity Analytics

Daily DEX/DeFi activity: trade count, trader count, volume USD, active DEX count

The analytics tools accept a `range` or a `from_date` / `to_date` window, and Transaction Analytics also takes a `filter`.

**Live-demo tools.** This is a hands-on sample of core Pro tools. They return the same real on-chain data as their Pro counterparts, under much stricter rate limits and request caps.

Tool

Returns

Account Transfer

SOL / SPL transfer history for an address

Account DeFi Activity

Swaps, liquidity, lending for an address

Account Transaction Enhanced

Transaction history with server-side filtering

Account Portfolio

Token holdings and USD value for an address

Token Transfer

Transfer history for a token

Token DeFi Activity

DeFi activity for a token

Token Meta

Metadata, supply, price, and market data for a token

Transaction Decode

Decoded actions for a transaction

### Things to ask your agent

Once it's connected, try prompts like these:

-   "How have Solana's daily priority fees trended over the last 30 days?"
-   "Show me the portfolio and USD value of this wallet."
-   "What DeFi activity has this token seen recently?"
-   "Decode this transaction and explain what it did."

### Get set up in three steps

1.  **Register a Solscan account** to get your free Level 1 API key.
2.  **Add the Public server to your MCP client.** For Claude Desktop, drop this into your config:

```json
{
  "mcpServers": {
    "solscan": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://public-mcp.solscan.io/mcp",
        "--header",
        "token:${SOLSCAN_API_KEY}"
      ],
      "env": {
        "SOLSCAN_API_KEY": "YourFreeApiKey"
      }
    }
  }
}
```

1.  **Restart your client and start asking.** Your agent can now call Solscan tools directly.

Endpoint: `https://public-mcp.solscan.io/mcp`

### Good to know

-   **Free tier, tight limits.** A Level 1 key has low rate limits and request caps. That's fine for testing and experimentation, but not for production traffic.
-   **A sample of Pro tools.** The live-demo set is a subset. The full tool set and advanced data live on the Pro server.
-   **No credit card.** Just register a Solscan account to get a Level 1 key.

### Ready for production?

When you're ready to build for real, switch to the **Pro server** at `https://mcp.solscan.io/mcp`. It has the full tool set, advanced data, and production limits.

Full setup guides for Claude Desktop, Claude Code, and Codex are in the [Solscan MCP docs](https://docs.solscan.io/build-with-ai/solscan-mcp).
