Stone

What your agent can do

Stone gives your agent 21 tools it calls directly — pick the ones it needs, in Claude, Cursor, or any MCP client.

• →get_balance — Get account balance
• →list_transactions — List account transactions
• →get_statement — Get account statement for a period

// Your agent calls a tool directly — no glue code.
// CodeSpar's managed tier handles OAuth2, token rotation and rate limits.
const result = await session.call("get_balance", { /* ... */ });

Install

$ npm install @codespar/mcp-stone

Quickstart

Add this entry to your claude_desktop_config.json (or any MCP-compatible client config).

{
  "mcpServers": {
    "stone": {
      "command": "npx",
      "args": [
        "-y",
        "@codespar/mcp-stone"
      ],
      "env": {
        "STONE_CLIENT_SECRET": "<your_stone_client_secret>"
      }
    }
  }
}

After restart, your agent can call any of the 21 tools below — try get_balance first.
