Implementation Reference

• src/index.ts:222-256 (handler)

  Handler for the get_token_info tool, which queries an ERC-20 token's metadata and supply using ethers.js.

  async ({ token_address }) => {
    try {
      const provider = getProvider();
      const token = new ethers.Contract(token_address, TOKEN_ABI, provider);
  
      const [name, symbol, decimals, totalSupply] = await Promise.all([
        token.name(),
        token.symbol(),
        token.decimals(),
        token.totalSupply(),
      ]);
  
      // Check if we have deploy record
      const record = deployments.find(
        (d) => d.tokenAddress.toLowerCase() === token_address.toLowerCase()
      );
  
      const result: Record<string, unknown> = {
        token_address,
        name,
        symbol,
        decimals: Number(decimals),
        total_supply: ethers.formatUnits(totalSupply, decimals),
        explorer: `https://basescan.org/token/${token_address}`,
      };
  
      if (record) {
        result.owner = record.owner;
        result.deployer = record.deployer;
        result.deployed_at = new Date(record.timestamp * 1000).toISOString();
        result.was_gasless = record.usedPaymaster;
  
        // Get owner balance
        const ownerBalance = await token.balanceOf(record.owner);
        result.owner_balance = ethers.formatUnits(ownerBalance, decimals);

• src/index.ts:216-221 (registration)

  Registration of the get_token_info tool with its schema definition using zod.

  server.tool(
    "get_token_info",
    "Get info about a deployed ERC-20 token: name, symbol, decimals, total supply, and owner balance.",
    {
      token_address: z.string().describe("Token contract address on Base"),
    },
