  The 'check_honeypot' tool implementation using the server.tool registration method and the simulateHoneypot helper function.

  server.tool(
    "check_honeypot",
    "Check if a token on Base mainnet is a honeypot by simulating buy and sell via Uniswap V2 router. Returns buy/sell ability and estimated taxes.",
    {
      token_address: z.string().describe("Token contract address on Base mainnet"),
    },
    async ({ token_address }) => {
      try {
        const metadata = await getTokenMetadata(token_address);
        const result = await simulateHoneypot(token_address);
  
        return ok({
          token: token_address,
          metadata: metadata ? serializeBigInts(metadata) as Record<string, unknown> : null,
          honeypotCheck: result,
        });
      } catch (err) {
        return fail(`check_honeypot failed: ${err instanceof Error ? err.message : String(err)}`);
      }
    }
  );
