• mcp-server/src/index.ts:1209-1235 (handler)

  The handler implementation for the list_tools MCP tool, which fetches a catalog of tools from the API and formats them for the client.

  async () => {
    const url = `${API_BASE_URL}/api/tools/catalog`;
    const response = await fetch(url);
    const data = (await response.json()) as any;
  
    const lines: string[] = [];
    lines.push(`Agent Toolbelt — ${data.count} tools available:\n`);
  
    for (const tool of data.tools || []) {
      lines.push(`**${tool.name}** (v${tool.version})`);
      lines.push(`  ${tool.description}`);
      if (tool.metadata?.pricing) {
        lines.push(`  Pricing: ${tool.metadata.pricing}`);
      }
      lines.push(`  Endpoint: POST ${tool.endpoint}`);
      lines.push("");
    }
  
    return {
      content: [
        {
          type: "text" as const,
          text: lines.join("\n"),
        },
