Quick Start

import { createGovInfoClient } from '@us-legal-tools/govinfo-sdk';

// Initialize the client
const client = createGovInfoClient({
  apiKey: 'YOUR_API_KEY', // Get from https://api.data.gov/signup/
});

// Example: Search for documents
const searchResults = await client.search({
  query: 'climate change',
  pageSize: 10,
});

API Client Usage

Configuration

import { createGovInfoClient } from '@us-legal-tools/govinfo-sdk';

const client = createGovInfoClient({
  apiKey: 'YOUR_API_KEY',
  baseURL: 'https://api.govinfo.gov', // Optional, this is the default
  timeout: 30000, // Optional timeout in ms
});

Available Methods

The SDK provides methods for all GovInfo API endpoints. Methods will be auto-generated based on the OpenAPI specification.

MCP Server

The package includes an MCP server that can be used with Claude Desktop or other MCP-compatible applications.

Configuration

Add to your Claude Desktop configuration:

{
  "mcpServers": {
    "govinfo": {
      "command": "npx",
      "args": ["@us-legal-tools/govinfo-sdk/mcp"],
      "env": {
        "GOVINFO_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}

Available Tools

The MCP server exposes GovInfo API operations as tools that can be called by Claude or other MCP clients. Each API endpoint becomes a callable tool with appropriate parameters.
