Implementation Reference

• src/index.ts:1215-1243 (handler)

  Implements the revoke_delegate tool logic: retrieves the wallet and associated token account, then uses Solana's SPL token `revoke` instruction to remove delegate authority and returns the transaction signature.

  async function handleRevokeDelegate(args: any) {
    const { walletName, tokenMint } = args;
  
    const wallet = wallets.get(walletName);
    if (!wallet) {
      throw new Error(`Wallet '${walletName}' not found`);
    }
  
    ensureConnection();
    const tokenMintPubkey = new PublicKey(tokenMint);
  
    const tokenAccount = await getAssociatedTokenAddress(
      tokenMintPubkey,
      wallet.keypair.publicKey
    );
  
    const signature = await revoke(
      connection,
      wallet.keypair,
      tokenAccount,
      wallet.keypair
    );
  
    return {
      success: true,
      signature,
      explorerUrl: `https://explorer.solana.com/tx/${signature}?cluster=${currentNetwork}`
    };
  }

• src/index.ts:506-523 (schema)

  Defines the input schema for the revoke_delegate tool, requiring walletName and tokenMint parameters.

  {
    name: "revoke_delegate",
    description: "Revoke a delegate's authority to transfer tokens",
    inputSchema: {
      type: "object",
      properties: {
        walletName: {
          type: "string",
          description: "Name of the wallet that owns the tokens"
        },
        tokenMint: {
          type: "string",
          description: "Token mint address"
        }
      },
      required: ["walletName", "tokenMint"]
    }
  }

• src/index.ts:1357-1359 (registration)

  Registers the revoke_delegate tool handler by dispatching to handleRevokeDelegate in the main CallToolRequestSchema handler switch statement.

  case "revoke_delegate":
    result = await handleRevokeDelegate(args);
    break;
