MCP Server

Pellet ships an MCP (Model Context Protocol) server as @pelletfi/mcp on npm. Install it once, and your agent gets tools for every Pellet endpoint — list stables, inspect peg, fetch flows, request editorial briefings.

Every value the MCP server exposes is an Open-Ledger Intelligence (OLI) measurement — read directly from Tempo's public ledger, never aggregated from off-chain oracles. An agent calling Pellet's MCP is practicing OLI on your behalf. See What is OLI?.

Install

npm install -g @pelletfi/mcp

Configure

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "pellet": {
      "command": "npx",
      "args": ["@pelletfi/mcp"],
      "env": {
        "PELLET_KEY": "pk_live_...",
        "EVM_PRIVATE_KEY": "0x..."
      }
    }
  }
}

Two auth modes, pick one:

PELLET_KEY — Pellet Pro subscription key. Unlimited calls, no per-request cost.
EVM_PRIVATE_KEY — a Tempo-compatible private key holding pathUSD. Paid endpoints are settled via MPP automatically.

`list_stablecoins`	`GET /v1/stablecoins`	Free

Example session

Once installed, ask Claude anything natural:

"Which Tempo stable has the widest peg spread right now?"

Claude calls list_stablecoins, compares peg.spread_bps across the returned set, and responds. No extra glue code.

"Analyze frxUSD for me."

Claude calls analyze_stablecoin. If you're on Pro, the call is free. If you're paying per request, $0.05 pathUSD is debited from your wallet and Claude returns the full briefing.
