Implementation Reference

• src/index.ts:1155-1176 (handler)

  Handler function that parses input, checks if credential exists, deletes it from the in-memory store, and returns success message.

  private async handleDeleteCredential(args: unknown) {
    const params = DeleteCredentialSchema.parse(args);
    
    if (!credentialStore.has(params.credentialId)) {
      throw new McpError(
        ErrorCode.InvalidParams,
        `Credential ID '${params.credentialId}' not found`
      );
    }
  
    const credential = credentialStore.get(params.credentialId)!;
    credentialStore.delete(params.credentialId);
  
    return {
      content: [
        {
          type: 'text',
          text: `Credential '${params.credentialId}' (${credential.username}@${credential.host}) deleted successfully`,
        },
      ],
    };
  }

• src/index.ts:139-141 (schema)

  Zod schema defining the input parameters for the ssh_delete_credential tool: credentialId (string).

  const DeleteCredentialSchema = z.object({
    credentialId: z.string().describe('Credential ID to delete')
  });

• src/index.ts:398-407 (registration)

  Tool registration entry in the ListTools handler, defining name, description, and input schema.

    name: 'ssh_delete_credential',
    description: 'Delete a saved SSH credential',
    inputSchema: {
      type: 'object',
      properties: {
        credentialId: { type: 'string', description: 'Credential ID to delete' }
      },
      required: ['credentialId']
    },
  },

• src/index.ts:509-510 (registration)

  Dispatch case in the CallToolRequestHandler switch statement that routes to the handler.

  case 'ssh_delete_credential':
    return await this.handleDeleteCredential(args);
